whiteout

documentation

whiteout provides macros that erase the type of any value into an impl Trait for a given trait. This gives you a value that can only be use with the methods of that trait, and whose type is unnameable.

```rust

[macro_use] extern crate whiteout;

fn main() { let a = erase!(10, std:ops::Add); assert_eq!(a + 10, 20); } `` Since we sometimes want to use these values together,whiteout` provides both a one-time macro and a macro that produces a function which returns a consistent unnameable type, allowing multiple erased values to be used in conjunction. See the documentation for more info.
