SDK Extension for Rust stable

This extension contains various components of the Rust stable toolchain.

Mold

In order to use the (fast) mold linker:

1. Add org.freedesktop.Sdk.Extension.llvm13 along with this extension in order to get clang.
2. Add /usr/lib/sdk/llvm13/bin to append-path. See llvm13 SDK extension readme for more information.
3. Add .cargo/config.toml in the root of the repository with the following content:

[target.x86_64-unknown-linux-gnu]
linker = "clang"
rustflags = ["-C", "link-arg=-fuse-ld=/usr/lib/sdk/rust-stable/bin/mold"]

Note: llvm13 is needed until there is a release of gcc12.1. As soon as gcc12.1 is in the freedesktop sdk, gcc can be used instead of clang.

Debugging/Development

In order to use this extension in flatpak SDK environment you may add all provided tools in your PATH by executing first:

source /usr/lib/sdk/rust-stable/enable.sh
