Struct CacheConfig

Source

pub struct CacheConfig {
    pub max_bytes: u64,
    pub ttl: Option<Duration>,
}

Expand description

Tuning for the decoded-block cache. max_bytes bounds total resident pixel memory across all cached blocks (moka evicts via TinyLFU). ttl is opt-in; COG data is immutable so the default relies on capacity eviction.

Fields§

§max_bytes: u64

Resident decoded-pixel byte capacity; defaults to 512 MiB. Eviction is eventually consistent and does not account for caller-held clones or decode working buffers. A zero capacity disables retention.

§ttl: Option<Duration>

Optional lifetime of an inserted decoded block. Defaults to None, relying on capacity eviction and immutable source identities.
