Enum Fields

#[non_exhaustive]
pub enum Fields {
    Named(Braced<Field, Comma>),
    Unnamed(Parenthesized<Field, Comma>),
    Empty,
}

An item body declaration.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Named(Braced<Field, Comma>)

A regular body.

Unnamed(Parenthesized<Field, Comma>)

A tuple body.

Empty

An empty body.

Trait Implementations

impl Debug for Fields

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a Fields

type Item = &'a Field

The type of the elements being iterated over.

type IntoIter = Map<Iter<'a, (Field, Option<Comma>)>, fn(_: &(Field, Option<Comma>)) -> &Field>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl OptionSpanned for Fields

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for Fields

fn parse(p: &mut Parser<'_>) -> Result<Self, Error>

Parse the current item from the parser.

impl PartialEq for Fields

fn eq(&self, other: &Fields) -> 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.

impl ToTokens for Fields

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for Fields

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for Fields

impl StructuralPartialEq for Fields
