Struct GpuRate 

pub struct GpuRate { /* private fields */ }

One device’s rate, shared by every context clone and renderer on it.

Implementations

impl GpuRate

pub fn ms_per_unit_pixel(&self) -> Option<f64>

The rate in milliseconds per unit pixel, once seeded.

pub fn begin_calibration(&self) -> bool

Returns true once, telling the first caller before seeding to run the calibration draw.

pub fn seed(&self, measured_ms_per_unit_pixel: f64)

Seeds the rate at twice measured_ms_per_unit_pixel, allowing for a cold device.

pub fn abandon_calibration(&self)

Allows a later caller to calibrate again after a failed draw.

pub fn observe(&self, measured_ms: f64, unit_pixels: f64)

Folds in a frame of unit_pixels predicted cost that took at most measured_ms. A higher rate drops by at most a tenth, never below the calibration.

Trait Implementations

impl Debug for GpuRate

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

Formats the value using the given formatter.

impl Default for GpuRate

fn default() -> Self

Returns the “default value” for a type.
