//! Traits which provide generic, object-safe APIs for generating and verifying
//! digital signatures, which provide message authentication using public-key
//! cryptography.
//!
//! ## Minimum Supported Rust Version
//!
//! Rust **1.36** or higher.
//!
//! Minimum supported Rust version can be changed in the future, but it will be
//! done with a minor version bump.
//!
//! ## SemVer Policy
//!
//! - All on-by-default features of this library are covered by SemVer
//! - MSRV is considered exempt from SemVer as noted above
//! - The off-by-default features `derive-preview` and `digest-preview` are
//!   unstable "preview" features which are also considered exempt from SemVer.
//!   Breaking changes to these features will, like MSRV, be done with a minor
//!   version bump.
