Describes a source of indices used for drawing.

Variants

IndexBuffer

A buffer uploaded in video memory.

Fields

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

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

MultidrawElement

Use a multidraw indirect buffer with indices.

Fields

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

primitives: PrimitiveType

Type of primitives contained in the vertex source.

Methods
