Struct ScopedTimer 

pub struct ScopedTimer<C: Clock> { /* private fields */ }

A timer guard that observes its duration when dropped.

Built on top of Timer. Useful for ?-heavy async code where every early-return path would otherwise need to remember to call Timer::observe. Validation failures after the guard is created are still part of the recorded duration; if a code path should not record a sample, call ScopedTimer::cancel before the guard is dropped.

Implementations

impl<C: Clock> ScopedTimer<C>

pub fn cancel(self)

Cancel the guard so it does not observe a sample on drop.

Trait Implementations

impl<C: Clock> Drop for ScopedTimer<C>

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.
