Struct GpuBuffer 

pub struct GpuBuffer {
    pub buffer_type: GpuBufferType,
    /* private fields */
}

A CPU-side mock for a typed GPU buffer backed by a Vecu8`.

Fields

buffer_type: GpuBufferType

Logical type.

Implementations

impl GpuBuffer

pub fn new(buffer_type: GpuBufferType, size: usize) -> Self

Allocate a new zero-initialised buffer of size bytes.

pub fn size(&self) -> usize

Current size in bytes.

pub fn read(&self, offset: usize, dst: &mut [u8]) -> usize

Read bytes at offset into dst. Returns the number of bytes copied.

pub fn write(&mut self, offset: usize, src: &[u8]) -> usize

Write bytes from src at offset. Returns bytes written.

pub fn resize(&mut self, new_size: usize)

Resize the buffer (data is zero-initialised for new regions).

pub fn clear(&mut self)

Zero-fill the entire buffer.

pub fn map(&mut self) -> Option<&mut [u8]>

Map the buffer for direct slice access (returns None if already mapped).

pub fn unmap(&mut self)

Unmap the buffer.

pub fn is_mapped(&self) -> bool

True when the buffer is currently mapped.
