Struct CacheMetrics 

#[non_exhaustive]
pub struct CacheMetrics {
    pub tier1_hits: u64,
    pub tier2_hits: u64,
    pub misses: u64,
    pub evictions: u64,
}

Cache hit/miss metrics.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tier1_hits: u64

tier2_hits: u64

misses: u64

evictions: u64

impl CacheMetrics

pub fn total_hits(&self) -> u64

Total cache hits (tier 1 + tier 2).

pub fn hit_rate(&self) -> f64

Hit rate as a fraction (0.0 to 1.0).
