Adding support for unified rust cage/grate compilation through cargo by stupendoussuperpowers · Pull Request #627 · Lind-Project/lind-wasm

stupendoussuperpowers · 2026-01-23T21:47:06Z

Basic Changes

From the Rust book https://doc.rust-lang.org/book/ch14-05-extending-cargo.html:

Cargo is designed so that you can extend it with new subcommands without having to modify it. If a binary in your $PATH is named cargo-something, you can run it as if it were a Cargo subcommand by running cargo something

This PR adds the cargo-lind_compile script which compiles the crate using all the settings detailed in #577, runs wasm-opt on the output binary, and places this script in PATH for the docker images. This lets us compile a rust crate into a lind-compatible binary just using cargo lind_compile, without requiring any extra configurations such as .cargo/config.toml.

Non deterministic `--epoch-injection` with Rust

Depending on what functions/libraries already exist in the pre-optimized wasm binary, the wasm-opt --epoch-injection step injects either wasi_snapshot_preview1.epoch_callback or lind.epoch_callback to the final binary.

This issue does not exist with C code.

The linker in lind-common only exports wasi_snapshot_preview1.epoch_callback and therefore, the binaries that have lind.epoch_callback trigger runtime errors.

Delineating two examples,

Basic Hello World

 fn main() {
     println!("Hello, world!");
 }

Compiles to give:

Import[8]:
 - memory[0] pages: initial=19 max=1024 shared <- env.memory
 - func[0] sig=4 <__imported_wasi_lind_setjmp> <- lind.lind-setjmp
 - func[1] sig=2 <__imported_wasi_lind_longjmp> <- lind.lind-longjmp
 - func[2] sig=13 <__lind_make_syscall_trampoline> <- lind.make-syscall
 - func[3] sig=14 <__imported_lind_get_memory_base> <- lind.lind-get-memory-base
 - func[4] sig=14 <__imported_lind_get_cage_id> <- lind.lind-get-cage-id
 - func[5] sig=2 <__imported_wasi_snapshot_preview1_environ_get> <- wasi_snapshot_preview1.environ_get
 - func[6] sig=2 <__imported_wasi_snapshot_preview1_environ_sizes_get> <- wasi_snapshot_preview1.environ_sizes_get

wasm-opts into:

 - func[7] sig=8 <lind.epoch_callback> <- lind.epoch_callback
 - global[3] i64 mutable=1 <epoch> - init i64=0
 - global[3] -> "epoch"

Using std::env

use std::env;

fn main() {
    // Force WASI args imports to remain in the binary.
    // (We intentionally do not use the values, just force the import.)
    let _ = env::args().count();

    println!("Hello, world!");
}

Compiles into:

Import[10]:
 - memory[0] pages: initial=19 max=1024 shared <- env.memory
 - func[0] sig=2 <wasi::lib_generated::wasi_snapshot_preview1::args_sizes_get> <-  wasi_snapshot_preview1.args_sizes_get
 - func[1] sig=2 <wasi::lib_generated::wasi_snapshot_preview1::args_get> <- wasi_snapshot_preview1.args_get
 - func[2] sig=4 <__imported_wasi_lind_setjmp> <- lind.lind-setjmp
 - func[3] sig=2 <__imported_wasi_lind_longjmp> <- lind.lind-longjmp
 - func[4] sig=13 <__lind_make_syscall_trampoline> <- lind.make-syscall
 - func[5] sig=14 <__imported_lind_get_memory_base> <- lind.lind-get-memory-base
 - func[6] sig=14 <__imported_lind_get_cage_id> <- lind.lind-get-cage-id

wasm-opts into:

 - func[9] sig=8 <wasi_snapshot_preview1.epoch_callback> <- wasi_snapshot_preview1.epoch_callback
 - global[3] i64 mutable=1 <epoch> - init i64=0
 - global[3] -> "epoch"

To fix this, I added an export to lind.epoch_callback which does the same thing as the wasi_snapshot_preview1.epoch_callback, and this seems to solve the issue.

I could not find any documentation or source on how the --epoch-injection flags works, specifically on how it picks the namespace to use, so I wasn't able to investigate this discrepancy further. Tagging @qianxichen233 to help with this.

- Add cargo-lind_compile global binary - Add lind::epoch_callback in the linker

This is really helpful thanks for putting this up. Would like @qianxichen233 opinions on the callbacks.

qianxichen233 · 2026-01-25T01:28:41Z

See PR#631 for the fix

stupendoussuperpowers · 2026-01-25T01:50:22Z

Removed the epoch_callback change from this PR since yours handles that now.

This should be good to merge but we should update this doc first: https://github.com/Lind-Project/lind-wasm/blob/main/docs/contribute/compile-with-rust.md

Can you make it so it is just an easy how to on using your script at the top but still keeps the details after for people who want to learn more. Also lets link to this from getting-started.md
