auto_curry

Procedural macro for currying most functions in Rust. This procedural macro can be thought of as a complete version of the unfinished Rust library, cutlass.

add Example (/examples/add.rs):

``` rust use auto_curry::curry;

[curry]

fn add(a: i32, b: i32) -> i32 { a + b }

fn main() { assert_eq!(add(1)(2), 3);

println!("{} = {}", add(1)(2), 3);

} ```

How it expands:

As of version 0.1.0, the add function in the example above expands exactly to: rust fn add(a: i32) -> impl Fn(i32) -> i32 { move |b| { a + b } } As far as I am aware, this is the most performant expansion in stable rust.

Capabilities:

1. Can handle funtions with a self receiver.
2. Can handle functions with generics and GAT's.
3. Works on stable.

Known issues:

• waiting on impl_trait_in_fn_trait_return to be able to significantly optimize curried functions.
