== Why is this an issue?
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
[source,rust,diff-id=1,diff-type=noncompliant]
----
match &*text.to_ascii_lowercase() {
    "foo" => {},
    "Bar" => {}, // Noncompliant: This arm is unreachable.
    _ => {},
}
----

==== Compliant solution

[source,rust,diff-id=1,diff-type=compliant]
----
match &*text.to_ascii_lowercase() {
    "foo" => {},
    "bar" => {},
    _ => {},
}
