Enum Fields

pub enum Fields {
    Named(FieldsNamed),
    Unnamed(FieldsUnnamed),
    Unit,
}

Data stored within an enum variant or struct.

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

Syntax tree enum

This type is a syntax tree enum.

Variants

Named(FieldsNamed)

Named fields of a struct or struct variant such as Point { x: f64, y: f64 }.

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

Unnamed(FieldsUnnamed)

Unnamed fields of a tuple struct or tuple variant such as Some(T).

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

Unit

Unit struct or unit variant such as None.

Implementations

impl Fields

pub fn iter(&self) -> Iter<'_, Field, Comma>

Get an iterator over the Field items in this object. This iterator can be used to iterate over a named or unnamed struct or variant’s fields uniformly.

Trait Implementations

impl Clone for Fields

fn clone(&self) -> Fields

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fields

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

Formats the value using the given formatter.

impl From<FieldsNamed> for Fields

fn from(e: FieldsNamed) -> Fields

Converts to this type from the input type.

impl From<FieldsUnnamed> for Fields

fn from(e: FieldsUnnamed) -> Fields

Converts to this type from the input type.

impl Hash for Fields

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

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<'a> IntoIterator for &'a Fields

type Item = &'a Field

The type of the elements being iterated over.

type IntoIter = Iter<'a, Field, Comma>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

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, tokens: &mut Tokens)

Write self to the given Tokens.

fn into_tokens(self) -> Tokens

where Self: Sized,

Convert self directly into a Tokens object.

impl Eq for Fields

impl StructuralPartialEq for Fields
