Types ¶
type Middleware ¶
type Middleware struct {
// contains filtered or unexported fields
}
Middleware instruments exact Tool.Call boundaries without recording model arguments or results. It is immutable after construction and safe for concurrent use.
func NewMiddleware ¶
func NewMiddleware(config MiddlewareConfig) (Middleware, error)
NewMiddleware fixes instrument identity and provider binding once so every tool invocation contributes to the same telemetry series.
type MiddlewareConfig ¶
type MiddlewareConfig struct {
TracerProvider trace.TracerProvider
MeterProvider metric.MeterProvider
}
MiddlewareConfig takes providers rather than a tracer and meter so the choice of telemetry destination stays with the composition root. A nil provider falls back to the OpenTelemetry global, which is the convenient default for an application and the wrong one for a test that must observe only its own instruments.
