Changed

  • Minimum supported Rust version in now 1.65.
  • Conversions between Ruby's Time and Rust's SystemTime now preserve nanosecond precision.

Deprecated

Removed

Fixed

  • The fatal exception raised when a Rust function bound to Ruby panics can no longer be caught with rescue Exception.

Security

0.7.1 - 2024-06-30

Fixed

  • Building docs with Ruby 3.0

0.7.0 - 2024-06-30

Added

  • Thread, Ruby::thread_create/thread_create_from_fn and other thread APIs.

Changed

  • Closures/Functions used as Ruby blocks/procs take an additional first argument of &Ruby.

Deprecated

  • RArray::each. Please use ary.into_iter() or ary.enumeratorize("each", ()) instead.

0.5.5 - 2023-08-20

Changed

  • Support rb-sys' stable-api feature.
  • Minimum supported Rust version is 1.60.
  • Ruby 2.6 support requires enabling rb-sys' stable-api-compiled-fallback feature in your Cargo.toml like so: rb-sys = { version = "*", default-features = false, features = ["stable-api-compiled-fallback"] }

0.6.0 - 2023-07-28

Added

  • value::Opaque can be used to wrap a Ruby type to make it Send + Sync.
  • value::Lazy lazily initialises a Ruby value so it can be assigned to a static.
  • value::OpaqueId is a Send + Sync version of value::Id.
  • value::LazyId is an Id with a const constructor so can be assigned to a static and derefs to OpaqueId.
  • error::OpaqueError is a Send + Sync version of Error.
  • The #[magnus(opaque_attr_reader)] attribute can be set on Opaque wrapped fields of a struct when deriving TypedData to generate a method to return the inner value.
  • Ruby::init function to initialise Ruby when embedding Ruby in Rust that runs a function with Ruby initialised, passing &Ruby.
  • rb_assert!() macro to assert a Ruby expression evaluates to a truthy value.
  • Class::undef_default_alloc_func to remove a class' allocator function only if it is Ruby's default allocator function.
  • Class::obj_alloc and Class::define_alloc_func for allocating an object without calling initialize, and for defining an allocator function.
  • RTypedData::wrap_as & typed_data::Obj<T>::wrap_as can be used to dynamically set the class when wrapping Rust data in a Ruby object. This can be used to allow wrapped data to be subclassed in Ruby.
  • Exception::exception_class returns the class of an exception as an ExceptionClass.
  • The kwargs!() macro and KwArgs type can be used to pass keyword arguments to ReprValue::funcall, et al.

Changed

  • Minimum supported Rust version in now 1.61.
  • The bytes-crate feature has been renamed to bytes.
  • The rb-sys-interop feature has been renamed to rb-sys.
  • Ruby types are no longer Send or Sync. These types can be made Send & Sync with the deprecated-send-sync-value feature. This feature is meant to ease upgrading and will be removed with the next release.
  • Value's methods moved to the ReprValue trait.
  • typed_data::Obj<T> derefs to T so now T's methods can be called directly on typed_data::Obj<T>.
  • ReprValue and TryConvert added to magnus::prelude.
  • typed_data::Cmp, typed_data::Dup and typed_data::Inspect traits to help with implementing #<=>, #dup & #clone, and #inspect methods for wrapped structs.
  • Wrapped data must be Sync to enable frozen_shareable flag.
  • TypedData::class and TypedData::class_for now take a &Ruby argument.
  • DataTypeFunctions::mark and DataTypeFunctions::compact now take &gc::Marker and &gc::Compactor arguments respectively.
  • Init function marked with #[magnus::init] optionally takes a &Ruby argument.
  • Functions bound as Ruby methods with method!() and function!() optionally take &Ruby as a first argument.
  • The value returned from embed::init derefs to Ruby.
  • DataTypeBuilder::new/DataType::builder now take their name argument as a 'static CStr (see the magnus::data_type_builder! macro to construct a DataTypeBuilder with a 'static CStr name).
  • All methods on DataTypeBuilder are now const, so DataType can be constructed in a const context and be assigned to a static.
  • The #[wrap] and #[derive(TypedData)] macros now support setting the #[magnus(unsafe_generics)] attribute to allow deriving TypedData for types with generics. The derived implementation is not guaranteed to be correct.

Deprecated

  • typed_data::Obj::get as it is made redundant by the Deref implementation for typed_data::Obj.
  • The QTRUE, QFALSE, and QNIL constants. Please use value::qtrue(), value::qfalse(), and value::qnil().
  • Class::undef_alloc_func. Please use Class::undef_default_alloc_func.
  • Value::try_convert, prefer TryConvert::try_convert or T::try_convert.
  • Binding. To call methods on Ruby's binding, use ReprValue::funcall on a Value know to be an instance of Ruby's Binding class.
  • gc::{mark, mark_slice, mark_movable, location}, instead use gc::Marker::{mark, mark_slice, mark_movable} and Compactor::location.
  • RStruct::as_slice.

Removed

  • Inherent methods on RClass, import magnus::Class trait or magnus::prelude::*.
  • Into<Value>/From<T> for Value implementations, use IntoValue.

  • Error::runtime_error (use Error::new(exception::runtime_error(), msg)).

Fixed

  • RFloat::from_value now returns None when value is a Flonum.

0.5.3 - 2023-04-07

Added

  • Value::as_value method that can be called on any Ruby type (as all Ruby types deref to Value) as a forward-compatible way to convert a Ruby type to Value.

Fixed

  • Fixed compilation issue in RBignum on 32 bit platforms.

  • value::Id::new added to replace value::Id::from.
  • TypedData::class_for can be implemented to customise the class on a case by case basis when wrapping Rust data in a Ruby object.
  • The #[wrap] and #[derive(TypedData)] macros now allow setting #[magnus(class = "...")] on enum variants to customise the class per variant when wrapping enums in a Ruby object.
  • Value::funcall_public calls a public method, returning an error for a private or protected method.
  • error::Result<T> is shorthand for std::result::Result<T, Error>.
  • embed::setup to perform minimal initialisation of Ruby for environments where embed::init doesn't work.
  • The bytes-crate feature can be enabled to allow automatic conversions between bytes::Bytes and Ruby strings.

Changed

  • When converting Ruby values to RArray (or Vec<T>, [T; 1], or (T,)), an error will be returned if given a non-Array (or non-to_ary-able) value, rather than wrapping it in an array (see RArray::to_ary for the old behaviour).
  • r_typed_data::{DataType, DataTypeFunctions, DataTypeBuilder, TypedData} all moved to typed_data module, r_typed_data module removed. This should only affect DataTypeBuilder as it was the only one not exported at the crate root.

Fixed

  • 'wrapped' structs from #[wrap] and #[derive(TypedData)] macros will not generate warning: undefining the allocator of T_DATA class under Ruby 3.2

0.4.3 - 2022-12-07

Fixed

  • gc::mark_slice was skipping the last element of the slice.

0.4.2 - 2022-11-30

Fixed

  • Removed errant dbg!().

0.4.1 - 2022-11-29

Added

  • Value::funcall_with_block.
  • impl TryConvert for Exception and ExceptionClass.
  • Class trait (implemented for RClass and ExceptionClass).
  • define_error and Module::define_error helpers for defining an Exception Class.
  • RTypedData::wrap and RTypedData::get inherent methods for wrapping Rust types in Ruby objects.
  • Support for Ruby 3.2 preview.
  • Support for mswin platform (msvc) on Windows with Ruby 3.2 (in addition to the mingw support previously available for all Ruby versions on Windows).

Changed

  • Switched to rb-sys for low level bindings.
  • Rust types wrapped in Ruby objects must be Send.
  • Only function pointers (fn or non-capturing closure) are accepted as argument for Value::block_call. Use Proc::from_fn + Value::funcall_with_block for closures that capture variables.
  • Proc::new only accepts a function pointer, use Proc::from_fn for closures that capture variables.
  • ExceptionClass::default() now returns StandardError rather than RuntimeError.
  • TryConvert now takes Value by value (rather than a reference).

Deprecated

  • DataTypeBuilder::free_immediatly (use free_immediately).
  • free_immediatly attribute in wrap macro (use free_immediately).
  • free_immediatly in magnus attribute of derive(TypedData) macro (use free_immediately).

Removed

  • define_global_variable (use define_variable).

Fixed

  • Memory leak of the message when returning an Error to raise an exception.

  • Fixed crash in Proc::new and Value::block_call when the proc was stored and called later.

0.3.1 - 2022-05-21

Fixed

  • Integer overflow in Ruby Float to f64 conversion

0.3.0 - 2022-05-18

Added

  • RString::new_shared and RString::new_frozen.
  • encoding module, including encoding::Index and RbEncoding types.
  • RString::enc_coderange and related methods.
  • RString::codepoints and RString::char_bytes iterators over string contents.
  • The following methods for RArray: dup, concat, plus, delete, delete_at, resize, reverse, rotate, and sort.

  • Error::iter_break.
  • StaticSymbol::check and Id::check to check if a symbol exists.

Changed

  • RArray::cat, RArray::from_slice, and gc::mark_slice will accept a slice of any Ruby type as an argument, rather than only a slice of Value. This may change type inference rules such that things like RArray::from_slice(&[1.into()]) will no longer work. Use RArray::from_slice(&[Value::from(1)]) instead.
  • Similar to above, gc::location will accept any Ruby type as an argument.
  • BoxValue can hold any Ruby type, not just Value.
  • Improved performance for conversion between Ruby floats/integers and Rust types.
  • The parameters to the closure passed to RHash::foreach will now be automatically converted from Value to Rust types.
  • Module::define_method, Module::define_private_method, Module::define_protected_method, RModule::define_singleton_method, and Object::define_singleton_method all return Result<(), Error> rather than () as they may fail in the unusual case that the receiver is frozen.

Deprecated

  • String::encode_utf8, use r_string.conv_enc(RbEncoding::utf8()) instead.
  • Value::leak, use gc::register_mark_object instead.
  • define_global_variable (use define_variable) to better match Ruby C API naming.
  • Exception::backtrace, use ex.funcall("backtrace", ()) instead.

Removed

  • error::protect removed as it should not be needed when using Magnus. For use with rb-sys enable the rb-sys-interop feature and use magnus::rb_sys::protect.
  • Qfalse::new, Qnil::new, Qtrue::new, Qundef::new (use QFALSE/QNIL/QTRUE/QUNDEF).
  • Functions for generating an Error with a specific Ruby type. E.g. Error::type_error("..."), use Error::new(exception::type_error(), "...").

Fixed

  • creating a StaticSymbol from a &str with characters outside the ASCII range.
  • panicking in any of the functions of DataTypeFunctions will abort the process to avoid undefined behaviour.
  • panicking in the closure passed to RHash::foreach won't result in undefined behaviour.

  • r_string! macro to create Ruby string from a str literal.
  • Value::equal and Value::eql for object equality.
  • Value::respond_to and Value::check_funcall for conditionally calling Ruby methods only when they are defined.
  • scan_args and get_kwargs for complex argument parsing.

Changed

  • Qundef::to_value now marked unsafe.
  • RArray::cat, RArray::push, RArray::unshift, and RArray::store now return Result<(), Error>.
  • eval! macro uses anonymous (rather than caller's) binding.

Deprecated

  • Qfalse::new, Qnil::new, Qtrue::new, Qundef::new (use QFALSE/QNIL/QTRUE/QUNDEF).
  • Functions for generating an Error with a specific Ruby type. E.g. Error::type_error("...") is now Error::new(exception::type_error(), "...")
  • Binding::new. This will be removed in the future as the underlying rb_binding_new will not function as of Ruby 3.2.

Fixed

  • Converting Ruby integers to isize/i64/usize/u64 on Windows.
  • Edge case where static symbol created after a dynamic symbol with the same name wouldn't be detected as static.
  • Many RArray methods now correctly protect from exceptions (instead returning Result<_, Error> when an exception occurs).

0.1.0 - 2022-02-25

Added

  • Support for most core classes, String, Symbol, Integer, Float, Array, Hash and more.
  • Defining Rust methods as Ruby functions.
