Use a different linker

[kevinheavey]

Is it possible to change the linker used? I'd like to try using mold on linux and lld on macOS

Did you encountered any issue when using a different linker? If you just want to know how to change the linker please refer to the documentation of Rust/Cargo, otherwise please provide more context, thanks.

I know how to use a different linker on my own machine. I can't see how to do it with maturin-action

The configuration should be similar to your local machine.

You just need to install mold before executing maturin-action on macOS and use before-script-linux option of maturin-action to install mold before executing maturin build in docker container.
