Struct ComputeBuffer 

pub struct ComputeBuffer {
    pub data: Vec<f32>,
    pub usage: BufferUsage,
    pub label: String,
}

A CPU-resident buffer that mirrors a GPU buffer.

Fields

data: Vec<f32>

Raw f32 elements.

usage: BufferUsage

Intended GPU usage hint.

label: String

Human-readable label (useful for debugging).

Implementations

impl ComputeBuffer

pub fn new(size: usize, usage: BufferUsage, label: &str) -> Self

Allocate a zero-initialised buffer of size f32 elements.

pub fn write_f32(&mut self, offset: usize, values: &[f32])

Write values into the buffer starting at element offset.

Panics

Panics if offset + values.len() > self.data.len().

pub fn read_f32(&self, offset: usize, count: usize) -> Vec<f32>

Read count f32 elements starting at element offset.

Panics

Panics if offset + count > self.data.len().

pub fn byte_size(&self) -> usize

Total size of the buffer in bytes (len * 4).

Trait Implementations

fn clone(&self) -> ComputeBuffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComputeBuffer

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