Point at the definition of non-covered enum variants.

Check that there are no borrow or move conflicts in binding @ subpat patterns.

A path pattern was interpreted as a constant, not a new variable. This caused an irrefutable match failure in e.g. let.

Check if a by-value binding is by-value. That is, check if the binding’s type is not Copy.

Report that a match is not exhaustive.

Checks for common cases of “catchall” patterns that may not be intended as such.

Report unreachable arms, if any.
