Struct luminance::buffer::Buffer

pub struct Buffer<T> { /* fields omitted */ }

A Buffer is a GPU region you can picture as an array. It has a static size and cannot be resized. The size is expressed in number of elements lying in the buffer, not in bytes.

Methods

impl<T> Buffer<T>

fn new(len: usize) -> Buffer<T>

Create a new Buffer with a given number of elements.

fn len(&self) -> usize

Get the length of the buffer.

fn at(&self, i: usize) -> Option<T> where T: Copy

Retrieve an element from the Buffer.

Checks boundaries.

fn whole(&self) -> Vec<T> where T: Copy

Retrieve the whole content of the Buffer.

fn set(&mut self, i: usize, x: T) -> Result<(), BufferError> where T: Copy

Set a value at a given index in the Buffer.

Checks boundaries.

fn write_whole(&self, values: &[T]) -> Result<(), BufferError>

Write a whole slice into a buffer.

If the slice you pass in as less items than the length of the buffer, you’ll get a BufferError::TooFewValues. If it has more, you’ll get BufferError::TooManyValues.

In all cases, the copy will be performed and clamped to reasonable length.

fn clear(&self, x: T) where T: Copy

Fill the Buffer with a single value.

fn fill(&self, values: &[T])

Fill the whole buffer with an array.

unsafe fn from_raw(raw: RawBuffer) -> Self

Create a new buffer from its raw representation.

This function is unsafe becomes it assumes that the representation is compliant to the type you want it to be.

fn to_raw(self) -> RawBuffer

Convert a buffer to its raw representation.

Methods from Deref<Target=RawBuffer>

fn as_slice<T>(&self) -> Result<BufferSlice<T>, BufferError>

Obtain an immutable slice view into the buffer.

fn as_slice_mut<T>(&mut self) -> Result<BufferSliceMut<T>, BufferError>

Obtain a mutable slice view into the buffer.

unsafe fn handle(&self) -> GLuint
