Struct nannou::ui::backend::glium::glium::index::IndexBufferAny [−][src]
pub struct IndexBufferAny { /* fields omitted */ }
An IndexBuffer
without any type information.
Makes it easier to store in a Vec
or return from a function, for example.
Methods
impl IndexBufferAny
[src]
impl IndexBufferAny
pub fn get_primitives_type(&self) -> PrimitiveType
[src]
pub fn get_primitives_type(&self) -> PrimitiveType
Returns the type of primitives associated with this index buffer.
pub fn get_indices_type(&self) -> IndexType
[src]
pub fn get_indices_type(&self) -> IndexType
Returns the data type of the indices inside this index buffer.
Methods from Deref<Target = BufferAny>
pub fn as_slice_any(&self) -> BufferAnySlice
[src]
pub fn as_slice_any(&self) -> BufferAnySlice
Builds a slice-any containing the whole subbuffer.
pub unsafe fn as_typed_slice_mut<T>(&mut self) -> BufferMutSlice<T> where
T: Content + ?Sized,
[src]
pub unsafe fn as_typed_slice_mut<T>(&mut self) -> BufferMutSlice<T> where
T: Content + ?Sized,
Builds a mutable typed slice containing the whole subbuffer, without checking the type.
pub unsafe fn as_typed_slice<T>(&self) -> BufferSlice<T> where
T: Content + ?Sized,
[src]
pub unsafe fn as_typed_slice<T>(&self) -> BufferSlice<T> where
T: Content + ?Sized,
Builds a typed slice containing the whole subbuffer, without checking the type.
pub fn get_elements_size(&self) -> usize
[src]
pub fn get_elements_size(&self) -> usize
Returns the size in bytes of each element in the buffer.
pub fn get_elements_count(&self) -> usize
[src]
pub fn get_elements_count(&self) -> usize
Returns the number of elements in the buffer.
pub fn get_context(&self) -> &Rc<Context>
[src]
pub fn get_context(&self) -> &Rc<Context>
Returns the context corresponding to this buffer.
pub fn get_size(&self) -> usize
[src]
pub fn get_size(&self) -> usize
Returns the number of bytes in this subbuffer.
pub fn invalidate(&self)
[src]
pub fn invalidate(&self)
Invalidates the content of the buffer. The data becomes undefined.
This operation is a no-op if the backend doesn't support it and for persistent-mapped buffers.
pub unsafe fn read<T>(&self) -> Result<<T as Content>::Owned, ReadError> where
T: Content,
[src]
pub unsafe fn read<T>(&self) -> Result<<T as Content>::Owned, ReadError> where
T: Content,
UNSTABLE. This function can be removed at any moment without any further notice.
Considers that the buffer is filled with elements of type T
and reads them.
Panic
Panics if the size of the buffer is not a multiple of the size of the data.
For example, trying to read some (u8, u8, u8, u8)
s from a buffer of 7 bytes will panic.
