error: redundant reference in `assert_eq!` argument
--> tests/injection.rs:633:13
= note: `-D clippy::useless-borrows-in-formatting` implied by `-D warnings`
No code changed to cause this. ci.yml installs whatever rustup calls
stable and the tree pins no toolchain, so the gate moved under the
repository: `useless_borrows_in_formatting` fires on a line that has been
there since the injection tests were written, and `RUSTFLAGS: -D
warnings` turns it into a hard failure.
The borrow was never doing anything -- `{:?}` formats a String and a
&String identically -- so this is the lint being right, not a workaround
for it.
Verified against the toolchain CI actually resolved to (1.97.1, not the
1.85 in Cargo.toml's rust-version), all four gates the workflow runs:
fmt clean, clippy --all-targets --all-features clean with no other lint,
208 tests passing, and cargo deny reporting advisories/bans/licenses/
sources ok.
Worth separating from this fix: the failure was invisible until it
happened because the toolchain floats. Nothing here pins it, so the next
stable release can turn this repository red without a commit. A
rust-toolchain.toml would close that, at the cost of not seeing new lints
until it is bumped -- a policy call, not a bug fix, so it is not in here.
