Enum Compare 

pub enum Compare {
    Never,
    Less,
    Equal,
    LessEqual,
    Greater,
    NotEqual,
    GreaterEqual,
    Always,
}

How two values are compared; the left one is the fragment’s own (its depth or alpha, or the stencil reference), the right one what it is tested against.

Variants

Never

Never passes.

Less

Passes where less.

Equal

Passes where equal.

LessEqual

Passes where less than or equal.

Greater

Passes where greater.

NotEqual

Passes where not equal.

GreaterEqual

Passes where greater than or equal.

Always

Always passes.
