[][src]Macro std::matches

macro_rules! matches {
    ($ expression : expr, $ ($ pattern : pat) | + $ (if $ guard : expr) ?) => { ... };
}
🔬 This is a nightly-only experimental API. (matches_macro #65721)

Returns whether the given expression matches any of the given patterns.

Like in a match expression, the pattern can be optionally followed by if and a guard expression that has access to names bound by the pattern.

Examples

#![feature(matches_macro)]

let foo = 'f';
assert!(matches!(foo, 'A'..='Z' | 'a'..='z'));

let bar = Some(4);
assert!(matches!(bar, Some(x) if x > 2));Run
