# Dylint configuration. cargo-dylint reads `[workspace.metadata.dylint]`
# from this file (or, equivalently, from `Cargo.toml`). Keeping the table
# here keeps the workspace `Cargo.toml` focused on cargo-native metadata
# and makes the cache key for CI easy to compute (see the `dylint` job
# in `.github/workflows/ci.yml`).
#
# Run with: `cargo dylint --all -- --all-targets --workspace`
# or via the `just dylint` recipe.
