# GAT std A variant of Rust `std` traits that use GATs, as well as a macro to allow rewriting code to use these traits instead of the `std` equivalents. ## Why? 1) These traits provide a common base so crates can all use the same definitions, like with `num-traits` 2) `std` likely won't be able to change to use these traits for quite a while, if ever. This allows users to take advantage of GATs in their code smoothly despite that.
