# We aim to always test with the latest stable Rust toolchain, however we pin to a specific | |
# version like 1.70. Note that we only specify MAJOR.MINOR and not PATCH so that bugfixes still | |
# come automatically. If the version specified here is no longer the latest stable version, | |
# then please feel free to submit a PR that adjusts it along with the potential clippy fixes. | |
RUST_STABLE_VER: "1.77" # In quotes because otherwise (e.g.) 1.70 would be interpreted as 1.7 | |
# The purpose of checking with the minimum supported Rust toolchain is to detect its staleness. | |
# If the compilation fails, then the version specified here needs to be bumped up to reality. | |
# Be sure to also update the rust-version property in the workspace Cargo.toml file, | |
# plus all the README.md files of the affected packages. | |
RUST_MIN_VER: "1.70" | |
# List of packages that will be checked with the minimum supported Rust version. | |
# This should be limited to packages that are intended for publishing. | |
RUST_MIN_VER_PKGS: "-p parley -p fontique" | |
# List of features that depend on the standard library and will be excluded from no_std checks. | |
FEATURES_DEPENDING_ON_STD: "std,default,system" | |
# Rationale | |
# | |
# We don't run clippy with --all-targets because then even --lib and --bins are compiled with | |
# dev dependencies enabled, which does not match how they would be compiled by users. | |
# A dev dependency might enable a feature that we need for a regular dependency, | |
# and checking with --all-targets would not find our feature requirements lacking. | |
# This problem still applies to cargo resolver version 2. | |
# Thus we split all the targets into two steps, one with --lib --bins | |
# and another with --tests --benches --examples. | |
# Also, we can't give --lib --bins explicitly because then cargo will error on binary-only packages. | |
# Luckily the default behavior of cargo with no explicit targets is the same but without the error. | |
# | |
# We use cargo-hack for a similar reason. Cargo's --workspace will do feature unification across | |
# the whole workspace. While cargo-hack will instead check each workspace package separately. | |
# | |
# Using cargo-hack also allows us to more easily test the feature matrix of our packages. | |
# We use --each-feature & --optional-deps which will run a separate check for every feature. | |
# | |
# We use macos-14 explictly instead of macos-latest because: | |
# * macos-latest currently points to macos-12 | |
# * macos-14 comes with the M1 CPU which compiles our code much faster than the older runners | |
# This explicit dependency can be switched back to macos-latest once it points to macos-14, | |
# which is expected to happen sometime in Q2 FY24 (April – June 2024). | |
# https://github.blog/changelog/2024-01-30-github-actions-macos-14-sonoma-is-now-available/ | |
# | |
# The MSRV jobs run only cargo check because different clippy versions can disagree on goals and | |
# running tests introduces dev dependencies which may require a higher MSRV than the bare package. | |
# | |
# For no_std checks we target x86_64-unknown-none, because this target doesn't support std | |
# and as such will error out if our dependency tree accidentally tries to use std. | |
