Struct TracedAsyncRwLock 

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

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

Each lock is identified by a static name, recorded as the lock field on the utils.rwlock.read and utils.rwlock.write spans so wait time is attributable to a specific lock.

Implementations

impl<T> TracedAsyncRwLock<T>

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

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

pub async fn read(&self) -> AsyncRwLockReadGuard<'_, T>

Acquire a shared read guard, recording lock-wait time.

pub async fn write(&self) -> AsyncRwLockWriteGuard<'_, T>

Acquire an exclusive write guard, recording lock-wait time.
