BlockCacheConfig

Struct BlockCacheConfig

pub struct BlockCacheConfig { /* private fields */ }

Available on crate feature std only.

Expand description

Configuration of a BlockCache.

The default budget is zero, which disables caching.

Implementations§

impl BlockCacheConfig

pub fn new(budget: usize) -> BlockCacheConfig

A config with budget bytes of cache and default block size and shards.

pub fn with_budget(self, budget: usize) -> BlockCacheConfig

Bytes of block data the cache may hold; zero disables caching.

pub fn set_budget(&mut self, budget: usize) -> &mut BlockCacheConfig

Bytes of block data the cache may hold; zero disables caching.

pub fn with_block_size(self, block_size: NonZero<usize>) -> BlockCacheConfig

Size of one cached block (default 4 KiB).

pub fn set_block_size( &mut self, block_size: NonZero<usize>, ) -> &mut BlockCacheConfig

Size of one cached block (default 4 KiB).

pub fn maybe_with_shards( self, shards: Option<NonZero<usize>>, ) -> BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn maybe_set_shards( &mut self, shards: Option<NonZero<usize>>, ) -> &mut BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn with_shards(self, shards: NonZero<usize>) -> BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn set_shards(&mut self, shards: NonZero<usize>) -> &mut BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn without_shards(self) -> BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn unset_shards(&mut self) -> &mut BlockCacheConfig

Number of independently locked shards; None derives it from the available parallelism and the budget.

pub fn budget(&self) -> usize

Bytes of block data the cache may hold.

pub fn block_size(&self) -> NonZero<usize>

Size of one cached block.
