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

pub struct InputAssemblyState {
    pub topology: PrimitiveTopology,
    pub primitive_restart_enable: bool,
    pub _ne: NonExhaustive,
}

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

Fields

topology: PrimitiveTopology

The type of primitives.

When DynamicState::PrimitiveTopology is used, if the dynamic_primitive_topology_unrestricted device property is false, then the dynamically set primitive topology must belong to the same topology class as topology. In practice, this is simply the first word in the name of the topology.

The default value is PrimitiveTopology::TriangleList.

primitive_restart_enable: 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.

The default value is false.

_ne: NonExhaustive

Implementations

impl InputAssemblyState

pub fn new() -> Self

👎Deprecated since 0.34.0: use InputAssemblyState::default instead

👎Deprecated since 0.34.0

Sets the primitive topology.

pub fn primitive_restart_enable(self) -> Self

👎Deprecated since 0.34.0

Enables primitive restart.
