Rust

CoreAV needs Rust 1.89 or later. The version is rust-version in the workspace’s Cargo.toml, and a CI job checks that this version builds the workspace. A change that needs a newer Rust raises the version in the same change.

​
What CI builds and tests

The native binaries and the WebAssembly build are those of the npm package coreav. None of these artifacts is published yet (Install).

​
The npm package

The npm package needs Node 20 or later. It runs the native binary on Linux (x86-64 and arm64, glibc or musl), macOS (arm64 and x86-64) and Windows (x86-64), and the WebAssembly build elsewhere. Both give the same output, output files and exit statuses. The WebAssembly build reads local files only: an input that names a URL is refused with exit status 2. The npm package’s design note covers how the package picks a binary.

​
Known gaps

  • The fallback’s tests do not run on Windows yet (the 0.1.0 release issue).
  • The macOS wheel is built on macOS arm64 only. There is no x86-64 macOS wheel.
