Struct SingleFieldData 

struct SingleFieldData {
    rust_name: Ident,
    col_name: Ident,
    col_name_str: String,
    ty: Type,
    tuple_index: Option<Index>,
    needs_into_list: bool,
}

Data for ResolvedField::Single.

Fields

rust_name: Ident

Rust field name (for access).

col_name: Ident

Column name in the DataFrame.

col_name_str: String

Column name string.

ty: Type

Field type stored in the companion Vec<#ty>. For #[dataframe(as_list)] on a struct-typed field this is overridden to ::miniextendr_api::list::List — see needs_into_list.

tuple_index: Option<Index>

Index in tuple struct (None for named).

needs_into_list: bool

#[dataframe(as_list)] on a struct-typed field (#485 workaround). When true, the companion field type is overridden to List and From<Vec<Row>> calls IntoList::into_list() on each row value.

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.
