Struct CachedSource 

pub struct CachedSource<S: TemplateSource> { /* private fields */ }

LRU-cached wrapper around any TemplateSource.

On the first call for a given (name, locale, default_locale) triple the inner source is queried and the result is stored in the cache. Subsequent calls with the same triple return the cached value without touching the inner source.

The cache is bounded by capacity entries. When full, the least-recently used entry is evicted.

Implementations

impl<S: TemplateSource> CachedSource<S>

pub fn new(inner: S, capacity: usize) -> Self

Create a new CachedSource wrapping inner with the given LRU capacity.

A capacity of 0 is treated as 1 to avoid a panic.

Trait Implementations

impl<S: TemplateSource> TemplateSource for CachedSource<S>

fn load(&self, name: &str, locale: &str, default_locale: &str) -> Result<String>

Load a template by name for the given locale.
