Struct TimestampNormalizer 

pub struct TimestampNormalizer {
    state: Option<InternalState>,
}

Normalizes GPU timestamps to have a consistent 1GHz period. See module documentation for more information.

Fields

state: Option<InternalState>

Implementations

impl TimestampNormalizer

pub fn new( device: &Device, timestamp_period: f32, ) -> Result<Self, TimestampNormalizerInitError>

Creates a new timestamp normalizer.

If the device cannot support automatic timestamp normalization, this will return a normalizer that does nothing.

Errors

If any resources are invalid, this will return an error.

pub unsafe fn create_normalization_bind_group( &self, device: &Device, buffer: &dyn DynBuffer, buffer_label: Option<&str>, buffer_size: BufferSize, buffer_usages: BufferUsages, ) -> Result<TimestampNormalizationBindGroup, DeviceError>

Create a bind group for normalizing timestamps in buffer.

buffer_size must be 4B-aligned, so that it is valid as a storage binding, must be the same or more than the application-visible buffer size, and must not overrun the buffer. This function is unsafe because it does not know and cannot check whether buffer_size meets these requirements.

The buffer size passed here is used to construct a binding that must be able to access the full application-visible range of the buffer. It is not used to check the destination range of query resolution requests. That uses the application-requested buffer size, obtained from the wgpu_core Buffer.

pub fn normalize( &self, snatch_guard: &SnatchGuard<'_>, encoder: &mut dyn DynCommandEncoder, tracker: &mut BufferTracker, bind_group: &TimestampNormalizationBindGroup, buffer: &Arc<Buffer>, buffer_offset_bytes: u64, total_timestamps: u32, )
