Struct GlobalSampleCache 

pub struct GlobalSampleCache { /* private fields */ }

Thread-safe, global cache for sampled values.

Implementations

impl GlobalSampleCache

pub fn new() -> Self

Creates a new, empty cache.

pub fn get(&self, key: &(usize, u64)) -> Option<SampledValue>

Gets a value from the cache.

pub fn insert(&self, key: (usize, u64), value: SampledValue)

Inserts a value into the cache.

pub fn get_or_compute<F>( &self, key: (usize, u64), compute_fn: F, ) -> Result<SampledValue, UncertainError>

where F: FnOnce() -> Result<SampledValue, UncertainError>,

Gets a value from the cache, or computes it if not present, then caches and returns it. This implementation includes a double-check to prevent redundant computation in concurrent scenarios.

pub fn clear(&self)

Clears all entries from the cache.

Trait Implementations

impl Debug for GlobalSampleCache

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

Formats the value using the given formatter.

impl Default for GlobalSampleCache

fn default() -> Self

Returns the “default value” for a type.
