runlimit-core 0.2.0

//! Framework-neutral contracts shared by Runlimit storage backends.
//!
//! This crate defines anchored fixed-window and GCRA policies, opaque subject
//! keys, checks, and backend-independent decisions. It deliberately contains
//! no async runtime, transport framework, or persistence integration.
//!
//! Applications own subject normalization and policy selection. Raw subjects
//! should be converted to [`SubjectKey`] values with [`KeyHasher`] before they
//! cross into a storage backend.
//! Async application adapters can use [`Limiter`] for generic dispatch across
//! storage backends without requiring boxed futures.
//!
//! The optional `serde` feature provides validated policy and response-metadata
//! wire types. Opaque [`SubjectKey`], [`CounterKey`], and
//! [`PolicyFingerprint`] values intentionally remain non-serializable.
