Struct TelemetryGuard 

pub struct TelemetryGuard { /* private fields */ }

RAII handle that flushes and shuts down the global tracer provider on drop.

Holding the guard for the lifetime of main() (CLI) or for as long as AppState is alive (HTTP server) ensures the final batch of spans is exported before the process exits.

Implementations

impl TelemetryGuard

pub fn noop() -> Self

Construct a noop guard. Drop is free.

pub fn with_timeout(self, timeout: Duration) -> Self

Override the flush+shutdown budget (mostly useful in tests).

pub fn has_provider(&self) -> bool

Test-only inspector: always false without telemetry.

Trait Implementations

impl Drop for TelemetryGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
