Struct Primitive 

pub struct Primitive {
    pub topology: Topology,
    pub streams: BTreeMap<Semantic, Stream>,
    pub indices: Option<Vec<u32>>,
    pub material: Option<Entity>,
}

One drawable part of a mesh: vertex streams, optional indices, a material. Primitives are kept in the game’s draw order (overlay stacking depends on it).

Fields

topology: Topology

streams: BTreeMap<Semantic, Stream>

Every stream has the same length (the vertex count). Position is required.

indices: Option<Vec<u32>>

Vertex indices; None means sequential.

material: Option<Entity>

The material entity, if any.

Implementations
