Macro stdext::unwrap_match

macro_rules! unwrap_match {
    ($var:expr, $variant:path) => { ... };
}

Similar to try_match but additionally unwraps the result.

Panics

Panics if expression didn’t match the provided path.

Examples

#[derive(Debug, PartialEq)]
enum Foo {
    Left(u16),
    Right(&'static str),
}

assert_eq!(unwrap_match!(Foo::Left(18), Foo::Left), 18);

The following example will panic:

assert_eq!(unwrap_match!(Foo::Right("nope"), Foo::Left), 18);
