Describes a source of indices used for drawing.

Variants

IndexBuffer

A buffer uploaded in video memory.

Fields of IndexBuffer

buffer: BufferAnySlice<'a>	The buffer.
data_type: IndexType	Type of indices in the buffer.
primitives: PrimitiveType	Type of primitives contained in the vertex source.

MultidrawArray

Use a multidraw indirect buffer without indices.

Fields of MultidrawArray

buffer: BufferAnySlice<'a>	The buffer.
primitives: PrimitiveType	Type of primitives contained in the vertex source.

MultidrawElement

Use a multidraw indirect buffer with indices.

Fields of MultidrawElement

commands: BufferAnySlice<'a>	The buffer of the commands.
indices: BufferAnySlice<'a>	The buffer of the indices.
data_type: IndexType	Type of indices in the buffer.
primitives: PrimitiveType	Type of primitives contained in the vertex source.

NoIndices

Don't use indices. Assemble primitives by using the order in which the vertices are in the vertices source.

Fields of NoIndices

primitives: PrimitiveType

Type of primitives contained in the vertex source.
