Container Style

Covers Structs, Tuplestructs and corresponding Newtypes.

Variants§

§

Struct(Vec<NamedStructField<'a>>)

Struct Container, e.g. struct Foo { a: String }

Variant contains the list of field identifiers and the corresponding extraction call.

§

StructNewtype(&'a Ident, Option<KeywordAttribute<from_py_with, LitStrValue<ExprPath>>>)

Newtype struct container, e.g. #[transparent] struct Foo { a: String }

The field specified by the identifier is extracted directly from the object.

§

Tuple(Vec<TupleStructField>)

Tuple struct, e.g. struct Foo(String).

Variant contains a list of conversion methods for each of the fields that are directly extracted from the tuple.

§

TupleNewtype(Option<KeywordAttribute<from_py_with, LitStrValue<ExprPath>>>)

Tuple newtype, e.g. #[transparent] struct Foo(String)

The wrapped field is directly extracted from the object.
