Struct syn::DataUnion

pub struct DataUnion {
    pub union_token: Union,
    pub fields: FieldsNamed,
}

An untagged union input to a proc_macro_derive macro.

This type is available only if Syn is built with the "derive" feature.

Fields

union_token: Union

fields: FieldsNamed

Trait Implementations

impl Clone for DataUnion

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataUnion

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<DataUnion> for Data

fn from(e: DataUnion) -> Data

Converts to this type from the input type.

impl Hash for DataUnion

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DataUnion

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
