}

One probed call. Plaintext never persists — fingerprints only.

Fields

provider: String

model: String

request_id: Option<String>

session_id: Option<String>

From CallOptions.session_id (RFC-0024) — explicit first, inference fallback; may also be the layer’s default session.

call_id: String

Call-level unique id (association key for Recording / replay, RFC-0023).

sent_at_unix_ms: i64

When the call was sent (epoch ms).

monotonic_sent_ms: u64

Monotonic clock ms (same domain as the store’s TTL lookups; internal bookkeeping, not part of the wire contract).

lcp_token_upper: Option<u64>

Client-side LCP token upper bound (block upper bound, byte-proxy len/4). None when no history matched. Consumed by TraceStats aggregation.

ttft_ms: Option<u64>

Time to first streamed token (ms). Non-streaming: None.

fingerprint: Fingerprint

usage: UsageSnapshot

response_cache_headers: Option<HashMap<String, String>>

Response-side cache headers (e.g. x-openrouter-cache-status).

request_cache_hints: Option<RequestCacheHints>

verdict: Option<Verdict>

Audit verdict (None when no auditor is attached — the default).

error: Option<String>

Error string when the call failed (still recorded: failures are part of the session).

scope_key: u64

Internal scope key (index only; never crosses the wire contract).

Implementations

impl TraceRecord

pub fn reported_hit_rate(&self) -> Option<f64>

Reported hit rate — strictly cache_read / input_total (RFC-0015 §5.2; never added to cache_write).

pub fn client_upper_bound_hit_rate(&self) -> Option<f64>

Client-side upper bound hit rate — token estimate / input_total.

Trait Implementations

impl Clone for TraceRecord

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TraceRecord

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for TraceRecord

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for TraceRecord

type WithoutGenerics = TraceRecord

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or ().
The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = TraceRecord

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident(cfg: &Config) -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name(cfg: &Config) -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete(cfg: &Config) -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl(cfg: &Config) -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline(cfg: &Config) -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened(cfg: &Config) -> String

Flatten a type declaration. This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported, relative to the output directory. The returned path does not include any base directory.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies(cfg: &Config) -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies. To export only this type, without its dependencies, use TS::export.

fn export_to_string(cfg: &Config) -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String. This function does not format the output, even if the format feature is enabled.
