pub struct IndirectParametersBuffer(pub BufferVec<IndirectParameters>);
Expand description
The buffer containing the list of IndirectParameters
, for draw commands.

Implementations§
source§impl IndirectParametersBuffer
impl IndirectParametersBuffer
sourcepub fn new() -> IndirectParametersBuffer
pub fn new() -> IndirectParametersBuffer
Creates the indirect parameters buffer.
Methods from Deref<Target = BufferVec<IndirectParameters>>§
sourcepub fn buffer(&self) -> Option<&Buffer>
pub fn buffer(&self) -> Option<&Buffer>
Returns a handle to the buffer, if the data has been uploaded.
sourcepub fn binding(&self) -> Option<BindingResource<'_>>
pub fn binding(&self) -> Option<BindingResource<'_>>
Returns the binding for the buffer if the data has been uploaded.
sourcepub fn capacity(&self) -> usize
pub fn capacity(&self) -> usize
Returns the amount of space that the GPU will use before reallocating.
sourcepub fn set_label(&mut self, label: Option<&str>)
pub fn set_label(&mut self, label: Option<&str>)
Changes the debugging label of the buffer.
The next time the buffer is updated (via [reserve
]), Bevy will inform
the driver of the new label.
sourcepub fn reserve(&mut self, capacity: usize, device: &RenderDevice)
pub fn reserve(&mut self, capacity: usize, device: &RenderDevice)
Creates a Buffer
on the RenderDevice
with size
at least std::mem::size_of::<T>() * capacity
, unless such a buffer already exists.
If a Buffer
exists, but is too small, references to it will be discarded,
and a new Buffer
will be created. Any previously created Buffer
s
that are no longer referenced will be deleted by the RenderDevice
once it is done using them (typically 1-2 frames).
In addition to any BufferUsages
provided when
the BufferVec
was created, the buffer on the RenderDevice
is marked as BufferUsages::COPY_DST
.
sourcepub fn write_buffer(&mut self, device: &RenderDevice, queue: &RenderQueue)
pub fn write_buffer(&mut self, device: &RenderDevice, queue: &RenderQueue)
Queues writing of data from system RAM to VRAM using the RenderDevice
and the provided RenderQueue
.
Before queuing the write, a reserve
operation is
executed.
