Struct TracedAsyncMutex 

pub struct TracedAsyncMutex<T> { /* private fields */ }

A Tokio-based async mutex whose acquisitions are recorded as tracing spans.

Each lock is identified by a static name, recorded as the lock field on the utils.mutex.lock span so wait time is attributable to a specific lock.

Implementations

impl<T> TracedAsyncMutex<T>

pub fn new(name: &'static str, value: T) -> Self

Create a new mutex wrapping value, identified by name in traces.

pub async fn lock(&self) -> AsyncMutexGuard<'_, T>

Acquire the mutex, recording lock-wait time.
