Struct vulkano::pipeline::graphics::input_assembly::InputAssemblyState

pub struct InputAssemblyState {
    pub topology: PartialStateMode<PrimitiveTopology, PrimitiveTopologyClass>,
    pub primitive_restart_enable: StateMode<bool>,
}

The state in a graphics pipeline describing how the input assembly stage should behave.

Fields

topology: PartialStateMode<PrimitiveTopology, PrimitiveTopologyClass>

The type of primitives.

Note that some topologies require a feature to be enabled on the device.

If set to Dynamic, the device API version must be at least 1.3, or the extended_dynamic_state feature must be enabled on the device.

primitive_restart_enable: StateMode<bool>

If true, then when drawing with an index buffer, the special index value consisting of the maximum unsigned value (0xff, 0xffff or 0xffffffff) will tell the GPU that it is the end of the current primitive. A new primitive will restart at the next index.

Primitive restart is mostly useful in combination with “strip” and “fan” topologies. “List” topologies require a feature to be enabled on the device when combined with primitive restart.

If set to Dynamic, the device API version must be at least 1.3, or the extended_dynamic_state2 feature must be enabled on the device.

Implementations
