Struct Cache 

pub struct Cache { /* private fields */ }

Every value a render computed and chose to keep, under its content hash. A hit is the value the cold run wrote, so what is kept or evicted decides only what is computed again.

Implementations

impl Cache

pub fn new() -> Cache

pub fn holding(max_bytes: u64) -> Cache

pub fn max_bytes(&self) -> u64

pub fn set_max_bytes(&self, max_bytes: u64)

pub fn policy(&self) -> CachePolicy

What a render stores where it names no policy of its own.

pub fn set_policy(&self, policy: CachePolicy)

pub fn prune_policy(&self) -> PrunePolicy

pub fn set_prune_policy(&self, policy: PrunePolicy)

pub fn prune(&self, policy: PrunePolicy)

Evicts every entry policy names, and more where the cap still needs it.

pub fn clear(&self)

pub fn bytes(&self) -> u64

pub fn entries(&self) -> usize

pub fn evictions(&self) -> u64

pub fn holds(&self, key: Hash) -> bool
