A direct replacement for assert_eq for unordered collections
These macros are 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 shows only the differences, when possible (see below for an example of what the output
looks like).
NOTE: Specifying no-default-features will allow this crate to be used in a
no-std environment, but without the assert_eq_ordered_set macro.

assert_unordered = "0.2"
There are three macros in this crate that do roughly the same thing. To decide which of the three makes sense for your use case, please read the documentation on each macro:
```rust, shouldpanic use assertunordered::assertequnordered;
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:
text
thread 'tests::test' panicked at 'The left did not contain the same items as the right:
In left, not in right: "[MyType(1), MyType(5)]"
In right, not in left: "[MyType(0)]"'
