Moka Rust

Use these conventions for Rust in-memory caches built with moka-rs/moka.

Source Baseline

• Prefer released docs from docs.rs/moka, crates.io, and the matching GitHub release over older snippets.
• Current docs.rs baseline checked for this skill: moka 0.12.15.
• Moka provides thread-safe, concurrent in-memory caches inspired by Caffeine.
• Current MSRV checked for sync and future: Rust 1.71.1.
• At least one crate feature, sync or future, must be enabled.
• Moka can bound caches by maximum entry count or total weighted size, supports TTL/TTI and per-entry expiration, and supports eviction listeners.
• Moka returns cloned values from cache reads. Store Arc<T> when values are expensive to clone.
