Struct PrunePolicy 

pub struct PrunePolicy { /* private fields */ }

Size, count, and age policy for cache pruning.

Implementations

impl PrunePolicy

pub const fn new(max_bytes: ByteLimit) -> Self

Creates a byte-bounded policy.

pub const fn max_entries(self, limit: EntryLimit) -> Self

Adds a maximum entry count.

pub const fn max_unused_age(self, age: Duration) -> Self

Removes entries unused for at least age, even below capacity.

pub const fn byte_limit(self) -> ByteLimit

Returns the high byte watermark.

pub const fn entry_limit(self) -> Option<EntryLimit>

Returns the optional high entry watermark.

pub const fn unused_age(self) -> Option<Duration>

Returns the optional maximum unused age.

Trait Implementations

impl Clone for PrunePolicy

fn clone(&self) -> PrunePolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PrunePolicy

impl Debug for PrunePolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PrunePolicy

impl PartialEq for PrunePolicy

fn eq(&self, other: &PrunePolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
