Enum devise::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.

Tuple Fields of Named

0: FieldsNamed

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.

Tuple Fields of Unnamed

0: FieldsUnnamed

Unit

Unit struct or unit variant such as None.

Implementations

impl Fields

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

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>

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.
