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