Episode notes
Lint Configuration in Cargo.toml
- Configure lint rules in
Cargo.tomlfor a cleaner crate root and easier workspace-wide lint sharing. - This allows sharing lints across workspaces and reduces noise in crate root files.
Cargo vs. Rustc Concerns
- Placing lint configuration in Cargo.toml raises concerns about the separation of Cargo and Rustc.
- Non-Cargo build tools might not recognize these lint settings, causing build failures.
Cargo Registry Authentication
- Cargo's new credential providers enhance security for private registries.
- Utilize credential providers like keychain, libsecret, or custom scripts instead of storing tokens in files.
