pub struct Profiler { /* private fields */ }

Implementations

impl Profiler

pub fn register(&mut self, name: &str, budget: Duration) -> CounterId

pub fn try_register( &mut self, name: &str, budget: Duration, ) -> Option<CounterId>

Existing names retain their initial budget. Names are 1..=128 UTF-8 bytes.

pub fn record(&mut self, id: CounterId, duration: Duration)

pub fn try_record(&mut self, id: CounterId, duration: Duration) -> bool

pub fn measure<T>(&mut self, id: CounterId, f: impl FnOnce() -> T) -> T

Native convenience. Browser callers supply performance.now through measure_with_clock.

pub fn measure_with_clock<T>( &mut self, id: CounterId, now: impl FnMut() -> Duration, f: impl FnOnce() -> T, ) -> T

pub fn summary(&self, id: CounterId) -> Summary

pub fn try_summary(&self, id: CounterId) -> Option<Summary>
