[+] Show declaration

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

[−] Expand description

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)

[−] Expand description

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)

[−] Expand description

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

[−] Expand description

Unit struct or unit variant such as None.

Methods

impl Fields

[−]

Important traits for Iter<'a, T>

impl<'a, T> Iterator for Iter<'a, T> type Item = &'a T;

pub fn iter(&self) -> Iter<Field>

[−]

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 From<FieldsNamed> for Fields

[+]

fn from(e: FieldsNamed) -> Fields

[−]

Performs the conversion.

impl From<FieldsUnnamed> for Fields

[+]

fn from(e: FieldsUnnamed) -> Fields

[−]

Performs the conversion.

impl ToTokens for Fields

[+]

fn to_tokens(&self, tokens: &mut Tokens)

[−]

Write self to the given Tokens.

fn into_tokens(self) -> Tokens

[−]

Convert self directly into a Tokens object.

impl<'a> IntoIterator for &'a Fields

[+]

type Item = &'a Field

The type of the elements being iterated over.

type IntoIter = Iter<'a, Field>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

[−]

Creates an iterator from a value.
