-//! The crunchy unroller - deterministically unroll constant loops. For number "crunching".
-//!
-//! The Rust optimizer will unroll constant loops that don't use the loop variable, like this:
-//!
-//! ```ignore
-//! for _ in 0..100 {
-//! println!("Hello!");
-//! }
-//! ```
-//!
-//! However, using the loop variable will cause it to never unroll the loop. This is unfortunate because it means that you can't
-//! constant-fold the loop variable, and if you end up stomping on the registers it will have to do a load for each iteration.
-//! This crate ensures that your code is unrolled and const-folded. It only works on literals,
-//! unfortunately, but there's a work-around:
-//!
-//! ```ignore
-//! debug_assert_eq!(MY_CONSTANT, 100);
-//! unroll! {
-//! for i in 0..100 {
-//! println!("Iteration {}", i);
-//! }
-//! }
-//! ```
-//! This means that your tests will catch if you redefine the constant.
-//!
-//! To default maximum number of loops to unroll is `64`, but that can be easily increased using the cargo features:
-//!
-//! * `limit_128`
-//! * `limit_256`
-//! * `limit_512`
-//! * `limit_1024`
-//! * `limit_2048`
