Struct VariantInfo

pub(crate) struct VariantInfo {
    pub(crate) name: Ident,
    pub(crate) shape: VariantShape,
    pub(crate) fields: Vec<EnumResolvedField>,
    pub(crate) skipped_fields: Vec<Ident>,
}

Expand description

Parsed and resolved information about a single enum variant for DataFrame codegen.

Contains the variant’s name, shape (named/tuple/unit), resolved fields (after applying #[dataframe(...)] attributes and type classification), and any skipped field names (needed for complete destructure patterns in named variants).

Fields§

§name: Ident

Variant name.

§shape: VariantShape

Shape of this variant.

§fields: Vec<EnumResolvedField>

Resolved fields (after applying field attrs + type classification).

§skipped_fields: Vec<Ident>

Original Rust field names (for named variants) — needed for skipped fields in destructure.

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.
