Type Alias CompareFunction 

pub type CompareFunction = CompareFunction;

Export compare function.

Aliased Type

#[repr(C)]
pub enum CompareFunction {
    Never = 1,
    Less = 2,
    Equal = 3,
    LessEqual = 4,
    Greater = 5,
    NotEqual = 6,
    GreaterEqual = 7,
    Always = 8,
}

Variants

Never = 1

Function never passes

Less = 2

Function passes if new value less than existing value

Equal = 3

Function passes if new value is equal to existing value. When using this compare function, make sure to mark your Vertex Shader’s @builtin(position) output as @invariant to prevent artifacting.

LessEqual = 4

Function passes if new value is less than or equal to existing value

Greater = 5

Function passes if new value is greater than existing value

NotEqual = 6

Function passes if new value is not equal to existing value. When using this compare function, make sure to mark your Vertex Shader’s @builtin(position) output as @invariant to prevent artifacting.

GreaterEqual = 7

Function passes if new value is greater than or equal to existing value

Always = 8

Function always passes
