Struct gfx_hal::pso::Specialization

pub struct Specialization<'a> {
    pub constants: Cow<'a, [SpecializationConstant]>,
    pub data: Cow<'a, [u8]>,
}

Information required for pipeline specialization.

Specialization allows for easy configuration of multiple similar pipelines. For example, there may be a boolean exposed to the shader that switches the specularity on/off, provided via a specialization constant.

That would produce separate PSO’s for the “on” and “off” states but they share most of the internal stuff and are fast to produce. More importantly, they are fast to execute, since the driver can optimize out the branch on that other PSO creation.

Fields

constants: Cow<'a, [SpecializationConstant]>

Array of descriptors of specialization constants to override.

data: Cow<'a, [u8]>

Raw data of the specialization constants

Implementations
