Struct TypedBuffer 

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

A GPU buffer with type-safe element tracking.

This wrapper adds:

• Type safety via generics
• Automatic length tracking
• Convenient write operations

The underlying buffer is directly accessible via the AsWgpu trait.

Implementations

impl<T: Pod> TypedBuffer<T>

pub fn new( device: &Device, label: Option<&str>, data: &[T], usage: BufferUsages, ) -> Self

Create a new typed buffer with initial data.

Arguments

• device - The wgpu device to create the buffer on
• label - Optional debug label for the buffer
• data - Initial data to populate the buffer with
• usage - Buffer usage flags

pub fn with_capacity( device: &Device, label: Option<&str>, capacity: u32, usage: BufferUsages, ) -> Self

Create an empty typed buffer with a given capacity.

Arguments

• device - The wgpu device to create the buffer on
• label - Optional debug label for the buffer
• capacity - Number of elements the buffer can hold
• usage - Buffer usage flags

pub fn len(&self) -> u32

Get the number of elements in the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn size(&self) -> u64

Get the size of the buffer in bytes.

pub fn capacity_bytes(&self) -> u64

Get the capacity of the buffer in bytes.

pub fn capacity(&self) -> u32

Get the capacity in number of elements.

pub fn usage(&self) -> BufferUsages

Get the buffer usage flags.

pub fn slice(&self) -> BufferSlice<'_>

Get a slice of the entire buffer.

pub fn slice_range(&self, range: Range<u32>) -> BufferSlice<'_>

Get a slice of a portion of the buffer.

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

Write data to the buffer.

The buffer must have been created with COPY_DST usage.

pub fn write_at(&self, queue: &Queue, offset: u32, data: &[T])

Write data to the buffer at an offset.

The buffer must have been created with COPY_DST usage.

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

Get the buffer as a binding resource (for bind groups).

pub fn buffer(&self) -> &Buffer

Get a reference to the underlying buffer.

impl<T: Pod> TypedBuffer<T>

pub fn new_uniform(device: &Device, label: Option<&str>, data: &T) -> Self

Create a new uniform buffer.

pub fn write_uniform(&self, queue: &Queue, data: &T)

Write a single uniform value to the buffer.

Trait Implementations

fn as_wgpu(&self) -> &Self::WgpuType

Get a reference to the underlying wgpu type.

impl<T: Pod> IntoWgpu for TypedBuffer<T>

type WgpuType = Buffer
