Release notes

Sourced from const_format's releases.

0.2.21 release

This release improves the assertion failure message for all the assertc* macros.

Example

Code:

#![feature(const_mut_refs)]
use const_format::{StrWriter, assertc_ne, writec};
use const_format::utils::str_eq;
macro_rules! check_valid_pizza{
($user:expr, $topping:expr) => {
assertc_ne!(
$topping,
"pineapple",
"You can't put pineapple on pizza, {}",
$user,
);
}
}
check_valid_pizza!("John", "salami");
check_valid_pizza!("Dave", "sausage");
check_valid_pizza!("Bob", "pineapple");

Error message before:

error: any use of this value will cause an error
  --> src/lib.rs:140:1
   |

   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ exceeded interpreter step limit (see `#[const_eval_limit]`)

Changelog

Sourced from const_format's changelog.

0.2.21

Rewrote assertion macros to:

• Have more concise error messages
• Point to all their arguments when the assertion fails
• Resemble std error messages more

0.2.19

Added char support to all formatting macros.

Added char, &[char], and Option<char> impls of FormatMarker trait, with debug formatting methods.

Added Formatter::{write_char, write_char_debug} methods.

Added StrWriterMut::{as_str_alt, write_char, write_char_debug} methods.

Added StrWriter::{as_str_alt, unsize} methods.

Deprecated strwriter_as_str macro, superceded by StrWriter::as_str_alt.

Bumped the minimum required nightly version to 2021-07-05 due to use of const-stabilized core::str::from_utf8_unchecked.

0.2.18

Fixed potential soundness bug where unions used to do pointer casts were not #[repr(C)]

0.2.16

Added these macros that act like str methods:

• str_get
• str_index
• str_repeat
• str_replace
• str_splice

Added the SplicedStr struct.

0.2.15

Added map_ascii_case macro to convert the casing style of a &'static str.

Added the Case enum.

Fixed "constant_time_as_str" crate feature in newer nightlies, this will break code that uses the feature and hasn't updated the nightly compiler to a release post mid-july 2021.

0.2.14
