-//! # simd-adler32
-//!
-//! A SIMD-accelerated Adler-32 hash algorithm implementation.
-//!
-//! ## Features
-//!
-//! - No dependencies
-//! - Support `no_std` (with `default-features = false`)
-//! - Runtime CPU feature detection (when `std` enabled)
-//! - Blazing fast performance on as many targets as possible (currently only x86 and x86_64)
-//! - Default to scalar implementation when simd not available
-//!
-//! ## Quick start
-//!
-//! > Cargo.toml
-//!
-//! ```toml
-//! [dependencies]
-//! simd-adler32 = "*"
-//! ```
-//!
-//! > example.rs
-//!
-//! ```rust
-//! use simd_adler32::Adler32;
-//!
-//! let mut adler = Adler32::new();
-//! adler.write(b"rust is pretty cool, man");
-//! let hash = adler.finish();
-//!
-//! println!("{}", hash);
-//! // 1921255656
-//! ```
-//!
-//! ## Feature flags
-//!
-//! * `std` - Enabled by default
-//!
-//! Enables std support, see [CPU Feature Detection](#cpu-feature-detection) for runtime
-//! detection support.
-//! * `nightly`
-//!
-//! Enables nightly features required for avx512 support.
-//!
-//! * `const-generics` - Enabled by default
-//!
-//! Enables const-generics support allowing for user-defined array hashing by value. See
-//! [`Adler32Hash`] for details.
-//!
-//! ## Support
-//!
-//! **CPU Features**
-//!
-//! | impl | arch | feature |
-//! | ---- | ---------------- | ------- |
-//! | ✅ | `x86`, `x86_64` | avx512 |
-//! | ✅ | `x86`, `x86_64` | avx2 |
-//! | ✅ | `x86`, `x86_64` | ssse3 |
-//! | ✅ | `x86`, `x86_64` | sse2 |
-//! | 🚧 | `arm`, `aarch64` | neon |
-//! | | `wasm32` | simd128 |
-//!
-//! **MSRV** `1.36.0`\*\*
-//!
-//! Minimum supported rust version is tested before a new version is published. [**] Feature
-//! `const-generics` needs to disabled to build on rustc versions `<1.51` which can be done
-//! by updating your dependency definition to the following.
-//!
-//! ## CPU Feature Detection
-//! simd-adler32 supports both runtime and compile time CPU feature detection using the
-//! `std::is_x86_feature_detected` macro when the `Adler32` struct is instantiated with
-//! the `new` fn.
-//!
-//! Without `std` feature enabled simd-adler32 falls back to compile time feature detection
-//! using `target-feature` or `target-cpu` flags supplied to rustc. See [https://rust-lang.github.io/packed_simd/perf-guide/target-feature/rustflags.html](https://rust-lang.github.io/packed_simd/perf-guide/target-feature/rustflags.html)
-//! for more information.
-//!
-//! Feature detection tries to use the fastest supported feature first.
