| # We use toolchain descriptors ("msrv", "stable", and "nightly") in the | |
| # matrix. This step converts the current descriptor to a particular | |
| # toolchain version by looking up the corresponding key in `Cargo.toml`. It | |
| # sets the `ZC_TOOLCHAIN` environment variable for future steps to use. | |
| # | |
| # Note that all metadata is stored in zerocopy's `Cargo.toml` (the one at | |
| # the repository root). zerocopy-derive is tested with the same versions, | |
| # and we have another CI job (see below) that makes sure that the | |
| # `package.rust_version` key in zerocopy-derive's `Cargo.toml` is the same | |
| # as the one in zerocopy's `Cargo.toml`. This key indicates the crate's | |
| # MSRV, and if this check weren't present, it would be possible for | |
| # zerocopy-derive to be published with an earlier MSRV than the one we test | |
| # for in CI - and thus potentially an MSRV that zerocopy-derive isn't | |
| # actually compatible with. | |
