Crate micro_moka 

Micro Moka is a lightweight cache library for Rust. Micro Moka is a fork of Mini Moka, stripped down to the bare essentials.

Micro Moka provides an in-memory, non-thread-safe cache implementation for single thread applications.

All cache implementations perform a best-effort bounding of the map using an entry replacement algorithm to determine which entries to evict when the capacity is exceeded.

Features

• A cache can be bounded by the maximum number of entries.
• Maintains good hit rate by using the SIEVE eviction algorithm (NSDI 2024), a lazy promotion, quick demotion algorithm with O(1) eviction.

Examples

See the following document:

• A not thread-safe, blocking cache for single threaded applications:
  • unsync::Cache

Minimum Supported Rust Versions

This crate’s minimum supported Rust versions (MSRV) are the followings:

Feature	MSRV
default features	Rust 1.76.0 (Feb 8, 2024)

If only the default features are enabled, MSRV will be updated conservatively. When using other features, MSRV might be updated more frequently, up to the latest stable. In both cases, increasing MSRV is not considered a semver-breaking change.

Modules

unsync

Provides a not thread-safe cache implementation built upon hashbrown::HashTable.
