Struct framehop::CacheStats

pub struct CacheStats {
    pub hit_count: u64,
    pub miss_empty_slot_count: u64,
    pub miss_wrong_modules_count: u64,
    pub miss_wrong_address_count: u64,
}

Statistics about the effectiveness of the rule cache.

Fields

hit_count: u64

The number of successful cache hits.

miss_empty_slot_count: u64

The number of cache misses that were due to an empty slot.

miss_wrong_modules_count: u64

The number of cache misses that were due to a filled slot whose module generation didn’t match the unwinder’s current module generation. (This means that either the unwinder’s modules have changed since the rule in this slot was stored, or the same cache is used with multiple unwinders and the unwinders are stomping on each other’s cache slots.)

miss_wrong_address_count: u64

The number of cache misses that were due to cache slot collisions of different addresses.
