Enum BufferUsage 

pub enum BufferUsage {
    StorageRead,
    StorageReadWrite,
    Uniform,
    Upload,
    Readback,
    Index,
    Vertex,
}

Describes how a GPU buffer will be used by the pipeline.

Variants

StorageRead

Read-only storage, typically for shader inputs.

StorageReadWrite

Read/write storage, for shader outputs or in-place ops.

Uniform

Uniform/constant data uploaded from the CPU.

Upload

Staging buffer for CPU→GPU uploads.

Readback

Staging buffer for GPU→CPU readback.

Index

Index buffer for draw calls.

Vertex

Vertex buffer for draw calls.

Implementations

impl BufferUsage

pub fn is_writable(&self) -> bool

Returns true when the pipeline may write to this buffer.

pub fn is_staging(&self) -> bool

Returns true when the buffer is used for transferring data between CPU and GPU (upload or readback).

pub fn label(&self) -> &'static str

Returns a human-readable label.

Trait Implementations

impl Clone for BufferUsage

fn clone(&self) -> BufferUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BufferUsage

impl Debug for BufferUsage

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

Formats the value using the given formatter.

impl Eq for BufferUsage

impl Hash for BufferUsage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BufferUsage

fn eq(&self, other: &BufferUsage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
