[−][src]Enum syn::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[src]

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

Notable traits for Iter<'a, T>

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

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

pub fn iter_mut(&mut self) -> IterMut<'_, Field>ⓘ

Notable traits for IterMut<'a, T>

impl<'a, T> Iterator for IterMut<'a, T> type Item = &'a mut T;
[src]

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