Struct BufferDescriptor

#[repr(C)]
pub struct BufferDescriptor<L> {
    pub label: L,
    pub size: BufferAddress,
    pub usage: BufferUsages,
    pub mapped_at_creation: bool,
}

Describes a Buffer.

Corresponds to WebGPU GPUBufferDescriptor.

Fields

label: L

Debug label of a buffer. This will show up in graphics debuggers for easy identification.

size: BufferAddress

Size of a buffer, in bytes.

usage: BufferUsages

Usages of a buffer. If the buffer is used in any way that isn’t specified here, the operation will panic.

mapped_at_creation: bool

Allows a buffer to be mapped immediately after they are made. It does not have to be BufferUsages::MAP_READ or BufferUsages::MAP_WRITE, all buffers are allowed to be mapped at creation.

If this is true, size must be a multiple of COPY_BUFFER_ALIGNMENT.

Implementations

impl<L> BufferDescriptor<L>

pub fn map_label<K>(&self, fun: impl FnOnce(&L) -> K) -> BufferDescriptor<K>

Takes a closure and maps the label of the buffer descriptor into another.

Trait Implementations

impl<L: Clone> Clone for BufferDescriptor<L>

fn clone(&self) -> BufferDescriptor<L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Debug> Debug for BufferDescriptor<L>

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

Formats the value using the given formatter.

impl<L: Hash> Hash for BufferDescriptor<L>

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<L: PartialEq> PartialEq for BufferDescriptor<L>

fn eq(&self, other: &BufferDescriptor<L>) -> 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.
