Enum EnumResolvedField 

pub(crate) enum EnumResolvedField {
    Single(Box<EnumSingleFieldData>),
    ExpandedFixed(Box<EnumExpandedFixedData>),
    ExpandedVec(Box<EnumExpandedVecData>),
    AutoExpandVec(Box<EnumAutoExpandVecData>),
    Map(Box<EnumMapFieldData>),
    Struct(Box<EnumStructFieldData>),
}

A resolved enum field ready for codegen – either a single column or expanded from an array/Vec into multiple suffixed columns.

This is the enum-path counterpart of ResolvedField (used for structs). Each variant carries both the binding name (for destructure patterns) and the original Rust field name (for error reporting and named-variant patterns).

Variants

Single(Box<EnumSingleFieldData>)

Single column contribution.

ExpandedFixed(Box<EnumExpandedFixedData>)

Expanded from [T; N].

ExpandedVec(Box<EnumExpandedVecData>)

Expanded from Vec with pinned width.

AutoExpandVec(Box<EnumAutoExpandVecData>)

Auto-expanded Vec/Box<[T]>: column count determined at runtime.

Map(Box<EnumMapFieldData>)

HashMap<K,V> or BTreeMap<K,V> → two parallel list-columns: <field>_keys, <field>_values.

Struct(Box<EnumStructFieldData>)

Struct field whose inner type implements DataFrameRow → flattened <base>_<inner_col> columns.

Implementations

impl EnumResolvedField

pub(crate) fn binding(&self) -> &Ident

Binding name used in destructure patterns.

pub(crate) fn rust_name(&self) -> &Ident

Original Rust field name.

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.
