[−][src]Struct syn::Field
A field of a struct or enum variant.
This type is available if Syn is built with the "derive" or "full"
feature.
Fields
attrs: Vec<Attribute>
Attributes tagged on the field.
vis: Visibility
Visibility of the field.
ident: Option<Ident>
Name of the field, if any.
Fields of tuple structs have no names.
colon_token: Option<Colon>
ty: Type
Type of the field.
Methods
impl Field[src]
impl Fieldpub fn parse_named(input: ParseStream) -> Result<Self>[src]
pub fn parse_named(input: ParseStream) -> Result<Self>Parses a named (braced struct) field.
pub fn parse_unnamed(input: ParseStream) -> Result<Self>[src]
pub fn parse_unnamed(input: ParseStream) -> Result<Self>Parses an unnamed (tuple struct) field.
