Struct CacheStats 

pub struct CacheStats {
    pub size: usize,
    pub max_size: usize,
    pub total_hits: usize,
    pub total_misses: usize,
}

Statistics about a regex cache.

Fields

size: usize

Current number of cached patterns.

max_size: usize

Maximum cache size.

total_hits: usize

Total cache hits.

total_misses: usize

Total cache misses.

Implementations

impl CacheStats

pub fn hit_rate(&self) -> f64

Get the cache hit rate as a ratio (0.0 to 1.0).

Returns 1.0 if no accesses have been made.

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 PartialEq for CacheStats

fn eq(&self, other: &CacheStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
