[−][src]Struct nannou::vk::pipeline::shader::SpecializationMapEntry

#[repr(C)]

pub struct SpecializationMapEntry {
    pub constant_id: u32,
    pub offset: u32,
    pub size: usize,
}

Describes an individual constant to set in the shader. Also a field in the struct.

Fields

constant_id: u32

Identifier of the constant in the shader that corresponds to this field.

For SPIR-V, this must be the value of the SpecId decoration applied to the specialization constant. For GLSL, this must be the value of N in the layout(constant_id = N) attribute applied to a constant.

offset: u32

Offset within the struct where the data can be found.

size: usize

Size of the data in bytes. Must match the size of the constant (4 for booleans).
