clippy::read_line_without_trim
Trim the line before parsing it: read_line keeps the trailing newline, so the parse always fails.

Not a defect when
The line is trimmed or stripped of its newline in a helper the lint does not follow before the parse sees it.
What it reads
Clippy, with the compiler behind it. The only pass that compiles.
Tier
Serious: worth interrupting other work for.
The tier bounds how severe a rule may be; its category bounds the tier.Diff scope
The changed line itself.
What--scope contextual looks at to decide whether a change caused the finding.Change it
Turn it off, or make it blocking, without touching the code it flags:
rust-doctor --rule clippy::read_line_without_trim=off .
rust-doctor --rule clippy::read_line_without_trim=error .
