Expand description
Data stored within an enum variant or struct.
This type is available only 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 }
.
Unnamed(FieldsUnnamed)
Unnamed fields of a tuple struct or tuple variant such as Some(T)
.
Unit
Unit struct or unit variant such as None
.
Implementations

impl Fields

pub fn iter(&self) -> Iter<'_, Field>ⓘNotable traits for Iter<'a, T>impl<'a, T> Iterator for Iter<'a, T> type Item = &'a T;
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;
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.
