-//! This crate provides traits which describe functionality of cryptographic hash
-//! functions and Message Authentication algorithms.
-//!
-//! Traits in this repository are organized into the following levels:
-//!
-//! - **High-level convenience traits**: [`Digest`], [`DynDigest`], [`Mac`].
-//! Wrappers around lower-level traits for most common use-cases. Users should
-//! usually prefer using these traits.
-//! - **Mid-level traits**: [`Update`], [`FixedOutput`], [`FixedOutputReset`],
-//! [`ExtendableOutput`], [`ExtendableOutputReset`], [`XofReader`],
-//! [`VariableOutput`], [`Reset`], [`KeyInit`], and [`InnerInit`]. These
-//! traits atomically describe available functionality of an algorithm.
-//! - **Marker traits**: [`HashMarker`], [`MacMarker`]. Used to distinguish
-//! different algorithm classes.
-//! - **Low-level traits** defined in the [`core_api`] module. These traits
-//! operate at a block-level and do not contain any built-in buffering.
-//! They are intended to be implemented by low-level algorithm providers only.
-//! Usually they should not be used in application-level code.
-//!
-//! Additionally hash functions implement traits from the standard library:
-//! [`Default`], [`Clone`], [`Write`][std::io::Write]. The latter is
-//! feature-gated behind `std` feature, which is usually enabled by default
-//! by hash implementation crates.
