Struct InMemoryCacheProvider

pub struct InMemoryCacheProvider { /* private fields */ }

In-memory cache provider

Uses LRU cache when “cache” feature is enabled, otherwise uses a simple HashMap.

Implementations

impl InMemoryCacheProvider

pub fn new(capacity: usize) -> Self

Create a new in-memory cache provider with specified capacity

pub fn with_default_capacity() -> Self

Create a new cache provider with default capacity (1000 items)
