assert_matches
Provides a macro, assert_matches
, which tests whether a value
matches a given pattern, causing a panic if the match fails.
#[macro_use] extern crate assert_matches;
#[derive(Debug)]
enum Foo {
A(i32),
B(i32),
}
let a = Foo::A(1);
assert_matches!(a, Foo::A(_));
assert_matches!(a, Foo::A(i) if i > 0);
To include in your project, only when tests are compiled, add the following to your Cargo.toml:
[dev-dependencies]
assert_matches = "1.5"
And add the following to your crate root:
#[cfg(test)] #[macro_use]
extern crate assert_matches;
