Struct glin::buffer_object::BufferObject

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

A mutable buffer object allocated with gl(Named)BufferData

Methods

impl<T: 'static> BufferObject<T>

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

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: Fn(&[T])>(&self, flags: MapReadFlags, f: F) -> Result<()>

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: Fn(&mut [T])>(     &mut self,     flags: MapWriteFlags,     f: F ) -> Result<()>

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: Fn(&mut [T])>(     &mut self,     flags: MapReadWriteFlags,     f: F ) -> Result<()>

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: BufferRange<U> + WithBackendMut<T>>(&self, dst: &mut B)

Copy one buffer into another

pub fn len(&self) -> usize

Number of elements on the last update

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) -> GLuint

OpenGL id

pub fn stride(&self) -> usize

Stride of the buffer type

pub fn to_shared(self) -> SharedBuffer<T>

Consume into a shared buffer

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

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: InputRange>(     &mut self,     range: R ) -> Range<T, BufferObject<T>, &mut BufferObject<T>>

Get a mutable range from the buffer

Useful to do operations on portions of the buffer

Panics if the range is out of bounds

pub fn to_range<R: InputRange>(     self,     range: R ) -> Range<T, BufferObject<T>, BufferObject<T>>

Consumes the buffer into a range

Panics if the range is out of bounds
