Struct Stats 

pub struct Stats {
    pub ok_count: u64,
    pub err_count: u64,
    /* private fields */
}

Timings for one (backend, operation) pair.

Fields

ok_count: u64

Totals over all time, unaffected by the window.

err_count: u64

Implementations

impl Stats

pub fn percentile(&self, p: f64) -> Option<u64>

The pth percentile of SUCCESSFUL calls, in microseconds.

None when nothing has succeeded — reporting 0 for an operation that has never completed would read as “instant” on exactly the dashboard someone uses to decide a cutover is safe.

pub fn error_percentile(&self, p: f64) -> Option<u64>

The same percentile over FAILED calls, for reading beside the successes.
