Install Rust nightly for aarch64:

Find out current rust version:

cat ./third_party/rust-toolchain/VERSION

Go to https://github.com/rust-lang/rust/commit/[hash] and figure out when the commit was made. Let's say 2024-02-14 in this case.

rm ./third_party/rust-toolchain/bin/rustc
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
ln -s $(which rustc) ./third_party/rust-toolchain/bin/rustc
