Struct StageTimings 

pub struct StageTimings { /* private fields */ }

Named synchronized GPU stage samples collected by a benchmark.

Implementations

impl StageTimings

pub fn new() -> Self

Create an empty collector.

pub fn measure<T>( &mut self, stream: &mut Stream, name: impl Into<String>, stage: impl FnOnce(&mut Stream) -> Result<T>, ) -> Result<T>

Synchronize, run one stage, synchronize again, and record elapsed milliseconds.

pub fn push(&mut self, name: impl Into<String>, milliseconds: f64) -> Result<()>

Add an already measured nonnegative millisecond sample.

pub fn distributions(&self) -> Result<BTreeMap<String, Distribution>>

Summarize each named stage in lexical order.

pub fn totals_ms(&self) -> BTreeMap<String, f64>

Sum the samples for every stage, in milliseconds.

pub fn take_totals_ms(&mut self) -> BTreeMap<String, f64>

Drain the samples and return each stage’s total milliseconds.

pub fn is_empty(&self) -> bool

Whether no stage samples have been recorded.

Trait Implementations

impl Default for StageTimings

fn default() -> Self

Returns the “default value” for a type.
