Class PromptResponseTrace

Request-local diagnostic trace. Callers pass it explicitly because the continuous scheduler interleaves rows and cannot safely use ambient async context. No instance is created unless MLX_BUN_P2R_TRACE=1.

Methods

begin

begin(
phase: P2RTracePhase,
attributes?: Readonly<Record<string, string | number | boolean | null>>,
): () => void
Start one span. The returned closer is idempotent so finally blocks and early exits cannot double-record a phase.
Parameters
- phase: P2RTracePhase
- Optionalattributes: Readonly<Record<string, string | number | boolean | null>>
Returns () => void
- Defined in packages/inference/src/runtime/trace.ts:105

finish

finish(
outcome: P2RTraceOutcome,
attributes?: Readonly<Record<string, string | number | boolean | null>>,
): P2RTraceRecord | null
Parameters
- outcome: P2RTraceOutcome
- Optionalattributes: Readonly<Record<string, string | number | boolean | null>>
Returns P2RTraceRecord | null
- Defined in packages/inference/src/runtime/trace.ts:131

mark

mark(
phase: P2RTracePhase,
attributes?: Readonly<Record<string, string | number | boolean | null>>,
): void
Parameters
- phase: P2RTracePhase
- Optionalattributes: Readonly<Record<string, string | number | boolean | null>>
Returns void
- Defined in packages/inference/src/runtime/trace.ts:121
