Struct GpuProfiler 

pub struct GpuProfiler { /* private fields */ }

Central GPU profiler that owns all active and completed timestamps.

Example

use oximedia_gpu::gpu_profiler::GpuProfiler;

let mut profiler = GpuProfiler::new();
profiler.begin("tonemap");
// ... GPU work ...
profiler.end("tonemap");
let summary = profiler.summary();
assert!(summary.contains_key("tonemap"));

Implementations

impl GpuProfiler

pub fn new() -> Self

Create a new, empty profiler.

pub fn begin(&mut self, label: impl Into<String>)

Begin a new profiling scope with the given label.

If a scope with this label is already active it is overwritten.

pub fn end(&mut self, label: &str)

End an active scope identified by label.

Records the elapsed time into cumulative stats. Does nothing if the label is not currently active.

pub fn scope(&mut self, label: impl Into<String>) -> GpuProfilerScope<'_>

Open a scope and return an RAII guard that calls end on drop.

pub fn summary(&self) -> &HashMap<String, ScopeStats>

Return a snapshot of the accumulated statistics for every scope.

pub fn reset(&mut self)

Reset all statistics and discard any active scopes.

pub fn scope_count(&self) -> usize

Return the number of distinct scope labels that have been recorded.

pub fn is_empty(&self) -> bool

Return true if there are no recorded statistics.
