//! A crate of useful macros used in `gix` primarily. //! //! Note that within `gix-*` crates, monomorphization should never be used for convenience, but only for performance //! reasons. And in the latter case, manual denomophization should be considered if the trait in questions isn't called //! often enough or measurements indicate that `&dyn Trait` is increasing the runtime. Thus, `gix-*` crates should probably //! by default prefer using `&dyn` unless measurements indicate otherwise. use proc_macro::TokenStream; /// When applied to functions or methods, it will turn it into a wrapper that will immediately call /// a de-monomorphized implementation (i.e. one that uses `&dyn Trait`). /// /// That way, the landing-pads for convenience will be as small as possible which then delegate to a single /// function or method for implementation. /// /// The parameters using the following traits can be de-monomorphized: /// /// * `Into` /// * `AsRef` /// * `AsMut` #[proc_macro_attribute] pub fn momo(_attrs: TokenStream, input: TokenStream) -> TokenStream { momo::inner(input.into()).into() } mod momo;
