Expand description

Builder for configuring a multi-tier backend.

Implementations§

Source§

impl<L1, L2> MultiTierBuilder<L1, L2>

Source

pub fn new() -> Self

Creates a new builder.

Source

pub fn l1(self, backend: L1) -> Self

Sets the L1 (fast) cache backend.

Source

pub fn l2(self, backend: L2) -> Self

Sets the L2 (persistent) cache backend.

Source

pub fn promotion_strategy(self, strategy: PromotionStrategy) -> Self

Sets the promotion strategy.

Source

pub fn promotion_threshold(self, threshold: u64) -> Self

Sets the promotion threshold for hit-count based promotion.

Source

pub fn write_through(self, enabled: bool) -> Self

Enables or disables write-through to L1.

Source

pub fn max_l1_entry_size(self, size: Option<usize>) -> Self

Sets the maximum entry size for L1 cache. Entries larger than this will only be stored in L2.

Source

pub fn build(self) -> MultiTierBackend<L1, L2>

Builds the multi-tier backend.
