Struct CacheEntry 

pub struct CacheEntry<T> {
    pub value: T,
    pub fetched_at: i64,
    pub expires_at: i64,
    pub etag: Option<String>,
}

A cached value together with its validity metadata.

T is the value type; when stored on disk the bytes are serde_json::to_vec(CacheEntry<serde_json::Value>).

Fields

value: T

The cached value.

fetched_at: i64

Unix timestamp (seconds) when the entry was written.

expires_at: i64

Unix timestamp (seconds) after which the entry is considered expired (i.e. fetched_at + ttl). A read between expires_at and expires_at + swr_window returns Freshness::Stale.

etag: Option<String>

ETag of the S3 object at fetch time, if available.
