Struct PresentStatsHandle 

pub struct PresentStatsHandle { /* private fields */ }

A shared slot the platform writes the latest PresentStats into.

Create one, clone it into the stats field of the window options, and keep the original to read the statistics of the most recent present while the window runs. The handle reports zeros until the first present.

Examples

use smudge_platform::PresentStatsHandle;

let handle = PresentStatsHandle::new();
let reader = handle.clone();
assert_eq!(reader.get().buffer_age, 0);

Implementations

impl PresentStatsHandle

pub fn new() -> PresentStatsHandle

Creates a handle that reports zeros until the first present.

pub fn get(&self) -> PresentStats

Returns the statistics of the most recent present.

pub fn adapter(&self) -> Option<AdapterSummary>

Returns the GPU adapter the window presents through, when it knows one.

The platform reports the adapter once, when it sets the GPU presentation path up, and only when the window was opened with a handle in its options. A window on the CPU renderer reports None, which is how a reader tells a GPU window from a CPU one.
