[][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 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 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 struct or unit variant such as None.

Methods

impl Fields
[src]

Important traits for Iter<'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.

Important traits for IterMut<'a, 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.
