Struct DrawArgs 

pub struct DrawArgs {
    pub vertex_count: u32,
    pub instance_count: u32,
    pub first_vertex: u32,
    pub first_instance: u32,
}

The four arguments of a non-indexed draw, as one value.

The non-indexed counterpart of DrawIndexedArgs, and the same argument in the same order as draw(vertexCount, instanceCount, firstVertex, firstInstance).

Fields

vertex_count: u32

The number of vertices to draw, taken from the bound vertex buffers as a non-indexed stream.

instance_count: u32

How many instances of the geometry to draw. 1 draws a single instance.

first_vertex: u32

The vertex to start from, for drawing a sub-range of the vertex stream.

first_instance: u32

The first instance index, for reading per-instance attributes from an offset.

Implementations

impl DrawArgs

Named constructors for the draw-argument structs, whose derived new skips every field and therefore takes no arguments.

pub fn whole_stream(vertex_count: u32, instance_count: u32) -> Self

A non-indexed draw of the whole vertex stream.

Arguments

• u32 - The number of vertices to draw.
• u32 - The number of instances to draw.

Returns

• Self - The assembled draw arguments, starting at vertex 0 of instance 0.
