As of the most recent cargo mutants version v25.2.0 delete match arm
and replace match guard mutations can now be identified on function
name patterns and as a result can be effectively excluded using the
existing mutation exclusion patterns.
The output of Display should not change in stable crates for types that
have well defined formatting and ones that implement FromStr.
Crates that are included in the mutation testing have been updated to
test all relevant Display implementations.
Remove the exclusion so that the Display implementations are included in
mutation testing.
cargo-mutants 25.0.1 introduced a new mutation pattern that deletes an
arm of a match statement or replaces a match guard with true and false.
These are applied in sections that have been excluded from mutation
testing and cause false positives.
The match patterns are also now stricter causing previously excluded
`impl` to be included.
Exclude the new match arm and guard mutation patterns.
Add `impl fmt::` versions for Debug and Display.
