Struct FileHttpCache 

pub struct FileHttpCache<T>
where
    T: Send + Sync + Serialize + for<'de> Deserialize<'de>,
{ /* private fields */ }

File-backed HTTP cache with a Fjall metadata index.

Layout under the provided base directory:

• index/: Fjall keyspace storing cache metadata keyed by cache key
• files/YYYY/MM/DD/*.json: full serialized CacheEntry<T> payloads
