Struct InputFallback 

pub struct InputFallback {
    pub value: InputFallbackValue,
    pub coordinate_copies: Option<FallbackCoordinateCopies>,
}

One source-stated input used only when a preceding stage cannot execute. The four base value forms cover normals, material colour, material coordinates and literals; optional copies retain the vertex program’s proved lane wiring. A consumer with no description supplies zero and names the missing input in its report.

Fields

value: InputFallbackValue

coordinate_copies: Option<FallbackCoordinateCopies>
