Struct glin::buffer_object::SharedBufferImmutable

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

Wrapper around a BufferObjectImmutable with internal reference counting

Useful for example when the same buffer or ranges of the same buffer are to be used in different VAOs

Methods

impl<T: 'static> SharedBufferImmutable<T>

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

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

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

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

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

pub fn len(&self) -> usize

pub fn capacity(&self) -> usize

pub fn bytes(&self) -> usize

pub fn capacity_bytes(&self) -> usize

pub fn id(&self) -> GLuint

pub fn stride(&self) -> usize

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

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