# Struct rustc_metadata::rmeta::VariantData

source ·

    struct VariantData {
        idx: VariantIdx,
        discr: VariantDiscr,
        ctor: Option<(CtorKind, DefIndex)>,
        is_non_exhaustive: bool,
    }

## Fields§

§`idx: VariantIdx`§`discr: VariantDiscr`§`ctor: Option<(CtorKind, DefIndex)>`

If this is unit or tuple-variant/struct, then this is the index of the ctor id.

§`is_non_exhaustive: bool`

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
