Request-time facts used to classify a cache miss without leaking prompt text.

Fields

provider: String

Canonical provider string associated with the request facts.

stable_prefix_length: usize

Number of stable prefix blocks observed in the request.

stable_prefix_tokens: Option<u32>

Token count for the stable prefix when it can be measured safely.

required_min_tokens: Option<u32>

Minimum provider threshold required for cache reuse.

first_mismatch_span_id: Option<String>

Span ID of the first stable block that mismatched the retained exemplar.

first_mismatch_sequence_index: Option<u32>

Sequence index of the first mismatching stable block.

expected_hash_prefix: Option<String>

Expected short SHA-256 hash prefix for the first mismatching block.

actual_hash_prefix: Option<String>

Actual short SHA-256 hash prefix for the first mismatching block.

retention_window_secs: Option<f64>

Active cache retention window in seconds when provider semantics expose one.

observed_gap_secs: Option<f64>

Observed elapsed time since the same stable prefix was last seen.

missing_facts: Vec<String>

Facts that were unavailable when the runtime attempted diagnosis.

Trait Implementations

impl Clone for CacheRequestFacts

fn clone(&self) -> CacheRequestFacts

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheRequestFacts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CacheRequestFacts

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheRequestFacts

fn eq(&self, other: &CacheRequestFacts) -> 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.

impl Serialize for CacheRequestFacts

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
