Struct CacheEntry 

pub struct CacheEntry {
    pub cid: String,
    pub data: Vec<u8>,
    pub inserted_at_secs: u64,
    pub last_accessed_secs: u64,
    pub access_count: u64,
}

A single cached block together with its bookkeeping metadata.

Fields

cid: String

Content identifier of the block.

data: Vec<u8>

Raw block bytes.

inserted_at_secs: u64

Unix timestamp (seconds) at which this entry was first inserted.

last_accessed_secs: u64

Unix timestamp (seconds) of the most recent cache hit; updated on every successful BlockCache::get call.

access_count: u64

Number of times this entry has been returned by BlockCache::get.

Implementations

impl CacheEntry

Returns true when the entry has lived longer than ttl_secs seconds relative to now_secs.

pub fn size_bytes(&self) -> usize

Returns the size of the cached data in bytes.
