Line range hint
43-50: Restore documentation and reconsider inlining strategy.The
#[inline]attribute may not provide significant benefits here due to:
- Async operations (mutex locking)
- Conditional notification logic
- Function size
Additionally, removing documentation for this core API method impacts usability.
Consider:
- Restoring the documentation:
+ /// Decrements the count of the latch, releasing all waiting tasks if the count reaches zero. + /// + /// If the current count is greater than zero, then it is decremented. If the new count is zero, + /// all waiting tasks are released. If the current count equals zero, then nothing happens. #[inline] pub async fn count_down(&self) {
- Using
#[inline(never)]instead, as this method might not be a good candidate for inlining due to its async nature and complexity.
Line range hint
52-59: Restore documentation and reconsider inlining for async wait.The
#[inline]attribute is unlikely to benefit this method due to:
- Multiple async operations
- Conditional logic and explicit resource management
- Function complexity
The removal of documentation impacts the understanding of this critical waiting behavior.
Consider:
- Restoring the documentation:
+ /// Causes the current task to wait until the latch has counted down to zero. + /// + /// If the current count is zero, this method returns immediately. + /// If the current count is greater than zero, the current task becomes disabled + /// for thread scheduling purposes and lies dormant until the count reaches zero. #[inline] pub async fn wait(&self) {
- Using
#[inline(never)]instead, as this method is not a good candidate for inlining due to its async nature and complexity.

35-64: Consider a more nuanced approach to performance optimization.While the addition of
#[inline]attributes shows attention to performance, a more nuanced approach would be beneficial:
- Async methods with complex logic (like
count_downandwait) might benefit more from#[inline(never)]to avoid code bloat.- Simple methods (like
newandwait_timeout) are good candidates for inlining.- Documentation is crucial for public APIs and should not be removed during optimization efforts.
Consider profiling the application to identify actual performance bottlenecks before applying broad optimizations.
