Struct EvalCache 

pub struct EvalCache { /* private fields */ }

Thread-safe cache for expression evaluation results with LRU eviction.

Uses DashMap for concurrent access and FxHasher for fast hashing.

Implementations

impl EvalCache

pub fn new() -> Self

Create a new evaluation cache with default size

pub fn with_capacity(max_size: usize) -> Self

Create a new evaluation cache with specified maximum size

pub fn get_or_compute<F>( &self, expr_hash: u64, params_hash: u64, compute: F, ) -> f64

where F: FnOnce() -> f64,

Get or compute an evaluation result

pub fn get(&self, expr_hash: u64, params_hash: u64) -> Option<f64>

Try to get a cached value without computing

pub fn get_or_try_compute<F, E>( &self, expr_hash: u64, params_hash: u64, compute: F, ) -> Result<f64, E>

where F: FnOnce() -> Result<f64, E>,

Get or compute with Result return type

pub fn insert(&self, expr_hash: u64, params_hash: u64, value: f64)

Insert a value into the cache

pub fn clear(&self)

Clear the cache

pub fn len(&self) -> usize

Get the number of cached entries

pub fn is_empty(&self) -> bool

Check if the cache is empty

pub fn stats(&self) -> CacheStats

Get cache statistics

Trait Implementations

impl Default for EvalCache

fn default() -> Self

Returns the “default value” for a type.
