Desktop migration: the home-manager rust here ships without the clippy component. Prefer an installed cargo-clippy; otherwise run clippy from an ephemeral nix-shell with a separate target dir (mixed-compiler artifacts are an E0514 hard error). MSRV keeps the shell's older toolchain a legitimate gate.

# smarm pre-commit gate: clippy the library (src/) with warnings as errors.
|

# unwrap_used / expect_used are denied (Cargo.toml [lints.clippy]): library
|
|
# code must not hide a panic behind unwrap/expect. Tests/examples are not gated.

# Toolchain resolution: prefer an installed cargo-clippy; on machines whose
|
|
# rust comes without the clippy component (e.g. NixOS home-manager), fall
|
|
# back to an ephemeral nix-shell toolchain. The fallback uses its own target
|
|
# dir (target/clippy) because the shell's rustc version may differ from the
|
|
# default toolchain's — mixed-compiler artifacts in one target dir are an
|
|
# E0514 hard error. MSRV (Cargo.toml rust-version) keeps the older shell
|
|
# toolchain a legitimate gate.
