assert_unordered

Crate Docs

A direct replacement for assert_eq for unordered collections

This macro is useful for any situation where the ordering of the collection doesn't matter, even if they are always in the same order. This is because the stdlib assert_eq shows the entire collection for both left and right and leaves it up to the user to visually scan for differences. In contrast, this crate only works with collections (types that implement IntoIterator) and therefore can show only the differences (see below for an example of what the output looks like).

NOTE: As of 0.3.2, the output by default is in color similar to pretty_assertions

Usage

NOTE: no-default-features can be used to disable color output (and enable no-std support)

toml [dev-dependencies] assert_unordered = "0.3"

Example

```rust, shouldpanic use assertunordered::assertequnordered;

[derive(Debug, PartialEq)]

struct MyType(i32);

fn main() { let expected = vec![MyType(1), MyType(2), MyType(4), MyType(5)]; let actual = vec![MyType(2), MyType(0), MyType(4)];

assert_eq_unordered!(expected, actual);

} ```

Output:

example_error
