Case mismatches in pattern arms make some arms unreachable, likely leading to logic errors that can be difficult to debug.
Code examples
Noncompliant code example
match &*text.to_ascii_lowercase() {
"foo" => {},
"Bar" => {}, // Noncompliant: This arm is unreachable.
_ => {},
}
Compliant solution
match &*text.to_ascii_lowercase() {
"foo" => {},
"bar" => {},
_ => {},
}
