Struct GpuBuffer 

pub struct GpuBuffer {
    pub data: Vec<f64>,
    pub size: usize,
}

A CPU-resident buffer that mimics a GPU storage buffer.

Fields

data: Vec<f64>

Buffer contents as f64.

size: usize

Declared capacity of the buffer (may differ from data.len() if the buffer was created with a fixed size but partially written).

Implementations

impl GpuBuffer

pub fn new(size: usize) -> Self

Create a zero-filled buffer of size elements.

pub fn from_data(initial_data: Vec<f64>) -> Self

Create a buffer pre-loaded with initial_data.

pub fn fill(&mut self, value: f64)

Fill the buffer with a constant value.

pub fn clear(&mut self)

Clear the buffer (set all elements to 0).

pub fn as_slice(&self) -> &[f64]

Get a slice of the buffer data.

pub fn as_mut_slice(&mut self) -> &mut [f64]

Get a mutable slice of the buffer data.

pub fn byte_size(&self) -> usize

Number of bytes the buffer would occupy on GPU (f64 = 8 bytes each).

Trait Implementations

impl Clone for GpuBuffer

fn clone(&self) -> GpuBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuBuffer

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

Formats the value using the given formatter.
