# New rust versions should first go to staging.
# Things to check after updating:
# 1. Rustc should produce rust binaries on x86_64-linux, aarch64-linux and x86_64-darwin:
#    i.e. nix-shell -p fd or @GrahamcOfBorg build fd on github
#    This testing can be also done by other volunteers as part of the pull
#    request review, in case platforms cannot be covered.
# 2. The LLVM version used for building should match with rust upstream.
#    Check the version number in the src/llvm-project git submodule in:
#    https://github.com/rust-lang/rust/blob/<version-tag>/.gitmodules

# Note: The way this is structured is:
# 1. Import default.nix, and apply arguments as needed for the file-defined function
# 2. Implicitly, all arguments to this file are applied to the function that is imported.
#    if you want to add an argument to default.nix's top-level function, but not the function
#    it instantiates, add it to the `removeAttrs` call below.
