Struct TypedBuffer 

pub struct TypedBuffer<T: Pod> { /* private fields */ }

A typed wrapper around wgpu::Buffer that tracks the element count so callers never have to compute byte sizes manually.

T must implement bytemuck::Pod — the same bound used by storage_buffer_init and read_back.

Example

use oxiui_compute_wgpu::buffer::TypedBuffer;

// Construction, upload, and download are all in element counts.

Implementations

impl<T: Pod> TypedBuffer<T>

pub fn new( device: &Device, label: &str, usage: BufferUsages, len: usize, ) -> Self

Allocate an uninitialised GPU buffer for len elements with the given usage flags.

pub fn from_data(device: &Device, label: &str, data: &[T]) -> Self

Create a STORAGE | COPY_DST | COPY_SRC buffer pre-filled with data.

pub fn len(&self) -> usize

Number of T elements the buffer holds.

pub fn is_empty(&self) -> bool

true if the buffer holds zero elements.

pub fn byte_len(&self) -> u64

Size of the buffer in bytes.

pub fn as_entire_binding(&self) -> BindingResource<'_>

Return a wgpu::BindingResource covering the entire buffer, suitable for passing to BindGroupEntry::resource.

pub fn inner(&self) -> &Buffer

Access the underlying wgpu::Buffer.

pub fn upload(&self, queue: &Queue, data: &[T])

Write data into the buffer via queue.write_buffer.

Panics

Panics if data.len() != self.len.

pub fn download(&self, device: &Device, queue: &Queue) -> Vec<T>

Read the buffer contents back to the CPU as a Vec<T>.
