Struct OutputUse 

pub struct OutputUse {
    pub label: Label,
    pub target: u32,
    pub blend_weight: u8,
    pub discard_tested: u8,
}

What a pixel program’s code and its target’s stated blend show of the lanes of one output that is a render target (iridia::output_uses::output_uses): observations, not roles. Each is a lane mask, bit k lane k.

Fields

label: Label

The output.

target: u32

The render target it is written to: its system value SV_Target<n>, or its label’s index where it has none.

blend_weight: u8

Lane 3 where the target’s stated blend weighs the colour by the source alpha (the colour equation’s source or destination factor is SrcAlpha or OneMinusSrcAlpha), else none.

discard_tested: u8

The lanes whose written value is among what a discard’s conditions are made of. A literal is no evidence (equal literals are one node of the value graph); none where the program’s value graph was not given.
