Enum Cache Miss Reason | NVIDIA NeMo Relay

Generated from cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi.

pub enum CacheMissReason {
    PrefixMismatch,
    BelowMinimumThreshold,
    RetentionExpired,
    RoutingMismatch,
    Evicted,
    UnsupportedFeature,
    ColdStart,
    Unknown,
    Other {
        description: String,
    },
}

Reason why a cache miss occurred.

Covers 8 determinable reasons plus an extensible Other variant. Uses internally-tagged JSON representation ("reason" field) so each variant serializes as {"reason": "snake_case"} and the Other variant additionally carries a description field.

Variants

`PrefixMismatch`

PrefixMismatch

Prompt prefix didn’t match cached prefix.

`BelowMinimumThreshold`

BelowMinimumThreshold

Stable prefix shorter than provider minimum for caching.

`RetentionExpired`

RetentionExpired

Cached prefix retention window elapsed.

`RoutingMismatch`

RoutingMismatch

Request routed to different worker/pool.

`Evicted`

Evicted

Cache evicted due to capacity pressure.

`UnsupportedFeature`

UnsupportedFeature

Backend/model doesn’t support caching.

`ColdStart`

ColdStart

First request for this prefix (no prior cache entry).

`Unknown`

Unknown

Reason could not be determined from provider response.

`Other`

Other

Extensible escape hatch for reasons not yet in the enum.

Fields

`description: String`

Human-readable description of the miss reason.
