Expand description

Represents a cache index entry, which points to content.

Fields§

§key: String

Key this entry is stored under.

§integrity: Integrity

Integrity hash for the stored data. Acts as a key into {cache}/content.

§time: u128

Timestamp in unix milliseconds when this entry was written.

§size: usize

Size of data associated with this entry.

§metadata: Value

Arbitrary JSON associated with this entry.

§raw_metadata: Option<Vec<u8>>

Raw metadata in binary form. Can be different from JSON metadata.
