Fields
ubo: Buffer<u8>
dirty: bool
Methods from Deref<Target = Buffer<u8>>
pub fn load(&mut self, data: &[T], usage: u32)
[src]
Loads the passed data into the buffer (re)allocating it
see: gl(Named)BufferData
pub fn load_target(&mut self, data: &[T], usage: u32, target: u32)
[src]
Loads the passed data into the buffer (re)allocating it to an specific target
see: gl(Named)BufferData
pub fn reserve(&mut self, len: usize, usage: u32)
[src]
Reserves len amount of memory into the buffer (re)allocating it
see: gl(Named)BufferData
pub fn reserve_target(&mut self, len: usize, usage: u32, target: u32)
[src]
Reserves len amount of memory into the buffer (re)allocating it to an specific target
see: gl(Named)BufferData
pub fn update(&mut self, data: &[T])
[src]
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(
&mut self,
flags: MapReadFlags
) -> Result<MapRead<'_, T, Buffer<T>>, Error>
[src]
&mut self,
flags: MapReadFlags
) -> Result<MapRead<'_, T, Buffer<T>>, Error>
Maps a buffer object’s data store
Pass a closure that receives the mapped buffer to access it
see glMapBuffer
pub fn map_write(
&mut self,
flags: MapWriteFlags
) -> Result<MapWrite<'_, T, Buffer<T>>, Error>
[src]
&mut self,
flags: MapWriteFlags
) -> Result<MapWrite<'_, T, Buffer<T>>, Error>
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(
&mut self,
flags: MapReadWriteFlags
) -> Result<MapReadWrite<'_, T, Buffer<T>>, Error>
[src]
&mut self,
flags: MapReadWriteFlags
) -> Result<MapReadWrite<'_, T, Buffer<T>>, Error>
Maps a buffer object’s data store
Pass a closure that receives the mapped buffer to access it
see glMapBuffer
pub unsafe fn map_read_slice(&self, flags: MapReadFlags) -> Result<&[T], Error>
[src]
Maps a buffer object’s data store as a slice
This operation is unsafe cause the buffer needs to be unmapped manually so it could be accessed while mapped which is undefined behaviour
see glMapBuffer
pub unsafe fn map_write_slice(
&mut self,
flags: MapWriteFlags
) -> Result<&mut [T], Error>
[src]
&mut self,
flags: MapWriteFlags
) -> Result<&mut [T], Error>
Maps a buffer object’s data store as a slice
This operation is unsafe cause the buffer needs to be unmapped manually so it could be accessed while mapped which is undefined behaviour
see glMapBuffer
pub unsafe fn map_read_write_slice(
&mut self,
flags: MapReadWriteFlags
) -> Result<&mut [T], Error>
[src]
&mut self,
flags: MapReadWriteFlags
) -> Result<&mut [T], Error>
Maps a buffer object’s data store as a slice
This operation is unsafe cause the buffer needs to be unmapped manually so it could be accessed while mapped which is undefined behaviour

pub unsafe fn unmap(&mut self)
[src]
pub fn copy_to<U, B>(&self, dst: &mut B) where
B: BufferRange<U> + WithBackendMut,
[src]
B: BufferRange<U> + WithBackendMut,
Copy one buffer into another
pub fn len(&self) -> usize
[src]
Number of elements on the last update
pub fn is_empty(&self) -> bool
[src]
If there’s no elements loaded in the buffer
This is len == 0 not capacity == 0
pub fn capacity(&self) -> usize
[src]
Allocated capacity of the buffer in number of elements
pub fn bytes(&self) -> usize
[src]
Total bytes on the last update
pub fn capacity_bytes(&self) -> usize
[src]
Total capcacity of the buffer in bytes
pub fn id(&self) -> u32
[src]
OpenGL id
pub fn stride(&self) -> usize
[src]
Stride of the buffer type
pub fn range<R>(&self, range: R) -> Range<T, Buffer<T>, &Buffer<T>> where
R: InputRange,
[src]
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,
[src]
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
