}

Fields

ubo: Buffer<CameraData>

dirty: bool

Methods from Deref<Target = Buffer<CameraData>>

pub fn load(&mut self, data: &[T], usage: u32)

Loads the passed data into the buffer (re)allocating it

see: gl(Named)BufferData

pub fn update(&mut self, data: &[T])

Loads the passed data at the beginning of the buffer

Will panic if the buffer is not big enough or not allocated at all

see: gl(Named)BufferSubData

pub fn map_read<F>(&self, flags: MapReadFlags, f: F) -> Result<(), Error> where     F: Fn(&[T]),

Maps a buffer object's data store

Pass a closure that receives the mapped buffer to access it

see glMapBuffer

pub fn map_write<F>(&mut self, flags: MapWriteFlags, f: F) -> Result<(), Error> where     F: Fn(&mut [T]),

Maps a buffer object's data store

Pass a closure that receives the mapped buffer to access it

see glMapBuffer

pub fn map_read_write<F>(     &mut self,     flags: MapReadWriteFlags,     f: F ) -> Result<(), Error> where     F: Fn(&mut [T]),

Maps a buffer object's data store

Pass a closure that receives the mapped buffer to access it

see glMapBuffer

pub fn copy_to<U, B>(&self, dst: &mut B) where     B: BufferRange<U> + WithBackendMut,

Copy one buffer into another

pub fn len(&self) -> usize

Number of elements on the last update

pub fn is_empty(&self) -> bool

If there's no elements loaded in the buffer

This is len == 0 not capacity == 0

pub fn capacity(&self) -> usize

Allocated capacity of the buffer in number of elements

pub fn bytes(&self) -> usize

Total bytes on the last update

pub fn capacity_bytes(&self) -> usize

Total capcacity of the buffer in bytes

pub fn id(&self) -> u32

OpenGL id

pub fn stride(&self) -> usize

Stride of the buffer type

pub fn range<R>(&self, range: R) -> Range<T, Buffer<T>, &Buffer<T>> where     R: InputRange,

Get a range from the buffer

Useful to do operations on portions of the buffer

Panics if the range is out of bounds

pub fn range_mut<R>(&mut self, range: R) -> Range<T, Buffer<T>, &mut Buffer<T>> where     R: InputRange,

Get a mutable range from the buffer

Useful to do operations on portions of the buffer

Panics if the range is out of bounds

Trait Implementations

impl Deref for CameraUBO

type Target = Buffer<CameraData>

The resulting type after dereferencing.

fn deref(&self) -> &Buffer<CameraData>

Dereferences the value.

impl DerefMut for CameraUBO

fn deref_mut(&mut self) -> &mut Buffer<CameraData>

Mutably dereferences the value.
