Struct StructFieldData 

struct StructFieldData {
    rust_name: Ident,
    col_name: Ident,
    col_name_str: String,
    inner_ty: Type,
    tuple_index: Option<Index>,
}

Data for ResolvedField::Struct.

A struct field whose inner type implements DataFrameRow. The companion struct holds Vec<Inner> (the same type users already pass into to_dataframe(vec![...])). At into_data_frame() time the inner rows are converted via Inner::to_dataframe → into_named_columns(), prefixed with <base_name>_, and pushed into the parent data.frame.

Fields

rust_name: Ident

Rust field name (for access on the row type).

col_name: Ident

Companion struct field name (ident).

col_name_str: String

Column name base used as the R-side prefix (<base>_<inner_col>).

inner_ty: Type

Inner struct type (used for to_dataframe dispatch + DataFrameRow assertion).

tuple_index: Option<Index>

Index in tuple struct (None for named).

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.
