-//! Fast, SIMD-accelerated CRC32 (IEEE) checksum computation.
-//!
-//! ## Usage
-//!
-//! ### Simple usage
-//!
-//! For simple use-cases, you can call the [`hash()`] convenience function to
-//! directly compute the CRC32 checksum for a given byte slice:
-//!
-//! ```rust
-//! let checksum = crc32fast::hash(b"foo bar baz");
-//! ```
-//!
-//! ### Advanced usage
-//!
-//! For use-cases that require more flexibility or performance, for example when
-//! processing large amounts of data, you can create and manipulate a [`Hasher`]:
-//!
-//! ```rust
-//! use crc32fast::Hasher;
-//!
-//! let mut hasher = Hasher::new();
-//! hasher.update(b"foo bar baz");
-//! let checksum = hasher.finalize();
-//! ```
-//!
-//! ## Performance
-//!
-//! This crate contains multiple CRC32 implementations:
-//!
-//! - A fast baseline implementation which processes up to 16 bytes per iteration
-//! - An optimized implementation for modern `x86` using `sse` and `pclmulqdq` instructions
-//!
-//! Calling the [`Hasher::new`] constructor at runtime will perform a feature detection to select the most
-//! optimal implementation for the current CPU feature set.
