Struct SpecializationConstant 

pub struct SpecializationConstant {
    pub name: String,
    pub value: String,
    pub id: u32,
}

A specialization constant that can be set at compile time. In OpenGL this is simulated via #define injection.

Fields

name: String

Constant name (becomes a #define).

value: String

Value as string (will be injected as-is).

id: u32

Constant ID (for Vulkan compatibility tracking).

Implementations

impl SpecializationConstant

pub fn int(name: &str, id: u32, value: i32) -> Self

Create a new integer specialization constant.

pub fn uint(name: &str, id: u32, value: u32) -> Self

Create a new unsigned integer specialization constant.

pub fn float(name: &str, id: u32, value: f32) -> Self

Create a new float specialization constant.

pub fn boolean(name: &str, id: u32, value: bool) -> Self

Create a boolean specialization constant (0 or 1).

pub fn apply(&self, source: &mut ShaderSource)

Apply this constant to a shader source as a define.

Trait Implementations

impl Clone for SpecializationConstant

fn clone(&self) -> SpecializationConstant

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpecializationConstant

fn fmt(&self, f: &mut Formatter<'_>) -> Result
