uhash-core 0.5.1

//! # uhash-core
//!
//! UniversalHash v4 — democratic proof-of-work hash engine.
//!
//! ## Primary API
//!
//! - [`hash`] — one-shot hash function
//! - [`UniversalHash`] — reusable hasher (avoids re-allocation)
//! - [`meets_difficulty`] / [`verify`] — proof verification
//! - [`build_input`] / [`challenge_input`] — challenge utilities
//!
//! ## no_std Support
//!
//! This crate supports `no_std` environments with the `alloc` crate:
//!
//! ```toml
//! [dependencies]
//! uhash-core = { version = "0.3", default-features = false }
//! ```
