Crate assert_let_bind

A convenience macro for writing pattern-matching tests in the Rust programming language.

The assert_let macro tests whether a value matches a given pattern, binding the pattern in the current scope if the match succeeds and causing a panic if the match //! fails.

(Strongly inspired by assert_matches)

use assert_let_bind::assert_let;

#[derive(Debug)]
enum Foo {
    A(i32, i32),
    B(i32),
}

let foo = Foo::A(3000, 2000);

assert_let!(Foo::A(x, y), foo);
assert_eq!(x + y, 5000);
