Struct nannou::wgpu::BufferUsage [−]
#[repr(transparent)]pub struct BufferUsage { /* fields omitted */ }
Different ways that you can use a buffer.
The usages determine what kind of memory the buffer is allocated from and what actions the buffer can partake in.
Implementations
impl BufferUsage
pub const MAP_READ: BufferUsage
Allow a buffer to be mapped for reading using [Buffer::map_async
] + [Buffer::get_mapped_range
].
This does not include creating a buffer with [BufferDescriptor::mapped_at_creation
] set.
If Features::MAPPABLE_PRIMARY_BUFFERS
isn’t enabled, the only other usage a buffer
may have is COPY_DST.
pub const MAP_WRITE: BufferUsage
Allow a buffer to be mapped for writing using [Buffer::map_async
] + [Buffer::get_mapped_range_mut
].
This does not include creating a buffer with mapped_at_creation
set.
If Features::MAPPABLE_PRIMARY_BUFFERS
feature isn’t enabled, the only other usage a buffer
may have is COPY_SRC.
pub const COPY_SRC: BufferUsage
Allow a buffer to be the source buffer for a [CommandEncoder::copy_buffer_to_buffer
] or [CommandEncoder::copy_buffer_to_texture
]
operation.
pub const COPY_DST: BufferUsage
Allow a buffer to be the destination buffer for a [CommandEncoder::copy_buffer_to_buffer
], [CommandEncoder::copy_texture_to_buffer
],
or [Queue::write_buffer
] operation.
pub const INDEX: BufferUsage
Allow a buffer to be the index buffer in a draw operation.
pub const VERTEX: BufferUsage
Allow a buffer to be the vertex buffer in a draw operation.
pub const UNIFORM: BufferUsage
Allow a buffer to be a BufferBindingType::Uniform
inside a bind group.
pub const STORAGE: BufferUsage
Allow a buffer to be a BufferBindingType::Storage
inside a bind group.
pub const INDIRECT: BufferUsage
Allow a buffer to be the indirect buffer in an indirect draw call.
pub const fn empty() -> BufferUsage
Returns an empty set of flags
pub const fn all() -> BufferUsage
Returns the set containing all flags.
pub const fn bits(&self) -> u32
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u32) -> Option<BufferUsage>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u32) -> BufferUsage
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u32) -> BufferUsage
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: BufferUsage) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: BufferUsage) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: BufferUsage)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: BufferUsage)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: BufferUsage)
Toggles the specified flags in-place.
pub fn set(&mut self, other: BufferUsage, value: bool)
Inserts or removes the specified flags depending on the passed value.
