Struct Buffer 

pub struct Buffer<'a> { /* private fields */ }

A buffer for sharing data between the CPU and GPU.

Create a buffer using the Device::create_buffer method.

Implementations

impl<'a> Buffer<'a>

pub fn size(&self) -> u32

Get the size of the buffer (in bytes).

pub fn output(&self) -> bool

Check if the buffer is an output buffer (i.e., readable from the CPU after being used by the GPU) or not.

pub fn data(&self) -> Option<&Vec<u8>>

Get a reference to the data stored in the buffer (as bytes).

pub fn buffer_type(&self) -> BufferType

Get the type of the buffer.

pub fn write<T>(&self, data: &T)

where T: ShaderType + WriteInto,

Write data to the buffer.

pub async fn read<T>(&self, output: &mut T) -> Result<(), BufferError>

where T: ShaderType + ReadFrom,

Read the data in the buffer. This makes the buffer temporarily accessible to the CPU to write the buffer contents to the output mutable reference.
