Struct PipelineOptions

pub struct PipelineOptions {
    pub allow_and_force_point_size: bool,
    pub vertex_pulling_transform: bool,
    pub vertex_buffer_mappings: Vec<VertexBufferMapping>,
}

A subset of options that are meant to be changed per pipeline.

Fields

allow_and_force_point_size: bool

Allow BuiltIn::PointSize and inject it if doesn’t exist.

Metal doesn’t like this for non-point primitive topologies and requires it for point primitive topologies.

Enable this for vertex shaders with point primitive topologies.

vertex_pulling_transform: bool

If set, when generating the Metal vertex shader, transform it to receive the vertex buffers, lengths, and vertex id as args, and bounds-check the vertex id and use the index into the vertex buffers to access attributes, rather than using Metal’s [[stage-in]] assembled attribute data. This is true by default, but remains configurable for use by tests via deserialization of this struct. There is no user-facing way to set this value.

vertex_buffer_mappings: Vec<VertexBufferMapping>

vertex_buffer_mappings are used during shader translation to support vertex pulling.
