Struct Timing 

pub struct Timing { /* private fields */ }

A clock started at one stage, charging what it measured when it stops.

The pair of calls is a type rather than two lines because the second line is the one that gets forgotten, and a stage that starts a clock and never stops it is a stage that reads as free.

Implementations

impl Timing

pub fn start(stage: Stage) -> Self

Starts the clock for a stage.

pub fn stop(self, bytes: u64)

Stops it and charges the time, along with the bytes that went through.

A caller with no meaningful byte count passes zero, which keeps the stage out of the rate column rather than putting a nought in it.

Trait Implementations

impl Debug for Timing

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
