Measured against /src/styleguide/rustguide.md:
- Each use statement imports from one module, and free functions are
called through theirs (db::step, db::now, jsonwebtoken::decode,
crate::feed::redact, unix::signal) rather than imported bare.
- unsafe_code is forbidden workspace-wide. The one unsafe was a test's
set_var, which is unsound while other tests' threads read the
environment; the test now reads PATH, which every run has.
- Locks say why they may panic: expect("a panic elsewhere poisoned this
lock") in place of 25 unwraps, and unique_slug's endless search says
it cannot end.
- No combinator chains in for headers: each is a named variable first.
- #[must_use] on the 27 functions clippy's must_use_candidate names.
- A literal bool passed where its meaning is not plain gets its name
(/* keep_open */ true, /* piece */ false, ...).
No behaviour changes.
