Enum gfx_hal::pso::PrimitiveRestart

pub enum PrimitiveRestart {
    Disabled,
    U16,
    U32,
}

Describes whether or not primitive restart is supported for an input assembler. Primitive restart is a feature that allows a mark to be placed in an index buffer where it is is "broken" into multiple pieces of geometry.

See https://www.khronos.org/opengl/wiki/Vertex_Rendering#Primitive_Restart for more detail.

Variants

Disabled

No primitive restart.

U16

Primitive restart using a 16-bit index value (std::u16::MAX).

U32

Primitive restart using a 32-bit index value (std::u32::MAX)

Trait Implementations

impl Ord for PrimitiveRestart

fn cmp(&self, other: &PrimitiveRestart) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self
