Struct glium::index::IndexBufferSlice
[−]
[src]
pub struct IndexBufferSlice<'a, T: 'a> where T: Index {
// some fields omitted
}Slice of an IndexBuffer.
Methods
impl<'a, T: 'a> IndexBufferSlice<'a, T> where T: Index
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.
fn slice(&self, range: Range<usize>) -> Option<IndexBufferSlice<'a, T>>
Returns None if out of range.
Methods from Deref<Target=BufferViewSlice<'a, [T]>>
fn get_size(&self) -> usize
Returns the size in bytes of this slice.
fn write(&self, data: &T)
Uploads some data in this buffer.
Panic
Panics if the length of data is different from the length of this buffer.
fn invalidate(&self)
Invalidates the content of the slice. The data becomes undefined.
This operation is a no-op if the backend doesn't support it.
fn read(&self) -> Result<T, ReadError>
Reads the content of the buffer.
fn as_slice_any(&self) -> BufferViewAnySlice<'a>
Builds a slice-any containing the whole subbuffer.
fn len(&self) -> usize
Returns the number of elements in this slice.
fn slice(&self, range: Range<usize>) -> Option<BufferViewSlice<'a, [T]>>
Builds a subslice of this slice. Returns None if out of range.
fn read_as_texture_1d<S>(&self) -> Result<S, ReadError> where S: Texture1dDataSink<T>
Reads the content of the buffer.
