This procedural macro crate provides a way to construct and annotate tuple types like arrays in Rust.

# Usage
```rust
!#[feature(proc_macro_hygiene)] // required for expansion to expressions

use fast_tuple::tuple;

fn main() {
    let tuple: tuple!(u32; 2) = tuple!(2; 2);
    println!("{}, {}", tuple.0, tuple.1); // prints 2, 2
}
```

# Version

This is a nigthly-only crate at the moment, unless you only use it for annotate types,this macro is also **no_std** only when debug assertions are disabled.
