Struct glin::buffer_object::BufferObjectImmutable

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

Inmmutable buffer object allocated with gl(Named)BufferStorage

Inmmutability here refers to the same concept OpenGL understands by it. The data in the buffer can still be modified but it can't be reallocated

Methods

impl<T: 'static> BufferObjectImmutable<T>

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])>(     &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])>(     &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) -> SharedBufferImmutable<T>

Consume into a shared buffer

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

Consumes the buffer into a range

Panics if the range is out of bounds
