Enum CacheId 

#[repr(u8)]
pub enum CacheId {
    AutorouteDecision = 0,
    AutorouteCalibration = 1,
    IncrementalUnchanged = 2,
    MatcherArtifact = 3,
    VerifierResult = 4,
}

A reuse cache the profiler reports hit and miss counts for.

Every KeyHog cache that exists to avoid repeating work reports through this one enum, so “what is our cache hit rate” has a single answer instead of one per subsystem. Record every consultation with exactly one of crate::record_cache_hit or crate::record_cache_miss, so the reported rate has a real denominator.

Counters are indexed by CacheId::index into a fixed array of length CacheId::COUNT, so recording is one relaxed atomic add with no allocation and no lookup on the hot path.

Variants

AutorouteDecision = 0

Persisted autoroute backend decision reused instead of re-deciding. A miss means the scan runs without a calibrated route.

AutorouteCalibration = 1

Autoroute calibration measurement reused instead of re-measuring.

IncrementalUnchanged = 2

Chunk skipped because the incremental scan judged it unchanged.

MatcherArtifact = 3

Compiled matcher artifact reused instead of recompiled. This is the cache standing between a scan and the engine-initialization cost.

VerifierResult = 4

Credential verification result reused instead of re-requested. A miss costs a network round trip, so this rate is also a rate-limit story.

Implementations

pub const fn index(self) -> usize

Dense index into the profiler’s per-shard counter arrays.

pub const fn as_str(self) -> &'static str

Stable text label used by profiles and operator reports.
