Build Status Docs

Tailcall is a library that adds safe, zero-cost tail recursion to stable Rust.

Eventually, it will be superseded by the become keyword.

Installation

Tailcall is distributed as a crate.

Add this to your Cargo.toml:

Usage

Add the tailcall attribute to functions which you would like to use tail recursion:

use tailcall::tailcall;

fn factorial(input: u64) -> u64 {
    #[tailcall]
    fn factorial_inner(accumulator: u64, input: u64) -> u64 {
        if input > 0 {
            factorial_inner(accumulator * input, input - 1)
        } else {
            accumulator
        }
    }

    factorial_inner(1, input)
}

For more detailed information, please see the docs.
