Struct CacheStats 

pub struct CacheStats {
    pub hits: usize,
    pub misses: usize,
    pub evictions: usize,
    pub memory_used: usize,
}

Cache statistics

Fields

hits: usize

Total cache hits

misses: usize

Total cache misses (an f64 create_optimizer call that reached the factory: no matching cached entry existed, or its config differed)

evictions: usize

Total evictions

memory_used: usize

Approximate memory used by currently cached instances, in bytes. Computed as sum(size_of_val(&*cached.plugin)) – the real, runtime size of each cached optimizer’s own concrete struct (resolved through its vtable, not guessed). This deliberately does not account for any heap allocations inside that struct (e.g. a Vec<f64> momentum buffer): this crate has no allocator instrumentation to attribute those bytes, and reporting only the immediate struct size is an honest undercount rather than a fabricated total.

Trait Implementations

impl Clone for CacheStats

fn clone(&self) -> CacheStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheStats

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

Formats the value using the given formatter.

impl Default for CacheStats

fn default() -> CacheStats

Returns the “default value” for a type.
