Specifying a toolchain with a date nightly-2023-09-30 and a rust-toolchain.toml

[tombh]

Here's the error, note that it is for aarch64-unknown-linux-gnu even though the generated toolchain name is for x86_64-unknown-linux-gnu:

Run /home/runner/work/_temp/cross +nightly-2023-09-30 build --locked --release --target aarch64-unknown-linux-gnu
error: error: invalid value 'nightly-2023-09-30-2023-09-30-x86_64-unknown-linux-gnu' for '<toolchain>...': invalid toolchain name: 'nightly-2023-09-30-2023-09-30-x86_64-unknown-linux-gnu'

It looks like cross honours rust-toolchain.toml and correctly provides the toolchain date (though the incorrect target). Whereas cargo requires setting the full nightly-2023-09-30 in the action's toolchain field.

I'm happy to look into this myself, just wondering if anybody has any insights?

Looks like this is a known issue in cross: cross-rs/cross#1541

[autarch]

I'm going to close this since it's a cross issue. Hopefully they'll do a release some time soon.
