Trait Implementations

impl Buffer for GlBuffer

fn usage(&self) -> BufferUsage

Returns usage kind of the buffer.

fn kind(&self) -> BufferKind

Returns buffer kind.

fn size(&self) -> usize

Returns total size of the buffer in bytes.

fn write_data(&self, data: &[u8]) -> Result<(), FrameworkError>

Writes an arbitrary number of bytes from the given slice.

fn read_data(&self, data: &mut [u8]) -> Result<(), FrameworkError>

Read an arbitrary number of bytes from the buffer (GPU memory) to the given slice. The amount of the data that will be attempted to read is defined by the length of the given slice.

impl Drop for GlBuffer

fn drop(&mut self)

Executes the destructor for this type.
