Struct glium::index::IndexBufferAny
[−]
[src]
pub struct IndexBufferAny {
// some 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]
fn get_primitives_type(&self) -> PrimitiveType
Returns the type of primitives associated with this index buffer.
fn get_indices_type(&self) -> IndexType
Returns the data type of the indices inside this index buffer.
Methods from Deref<Target=BufferAny>
fn as_slice_any(&self) -> BufferAnySlice
Builds a slice-any containing the whole subbuffer.
fn get_elements_size(&self) -> usize
Returns the size in bytes of each element in the buffer.
fn get_elements_count(&self) -> usize
Returns the number of elements in the buffer.
fn get_context(&self) -> &Rc<Context>
Returns the context corresponding to this buffer.
fn get_size(&self) -> usize
Returns the number of bytes in this subbuffer.
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.
unsafe fn read<T>(&self) -> Result<T::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
Panicks 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.
