pub struct Field {
pub attrs: Vec<Attribute>,
pub vis: Visibility,
pub ident: Option<Ident>,
pub colon_token: Option<Colon>,
pub ty: Type,
}Expand description
A field of a struct or enum variant.
This type is available only if Syn is built with the "derive" or "full"
feature.
Fields
attrs: Vec<Attribute>Attributes tagged on the field.
vis: VisibilityVisibility of the field.
ident: Option<Ident>Name of the field, if any.
Fields of tuple structs have no names.
colon_token: Option<Colon>ty: TypeType of the field.
Implementations
sourceimpl Field
impl Field
sourcepub fn parse_named(input: ParseStream<'_>) -> Result<Self>
pub fn parse_named(input: ParseStream<'_>) -> Result<Self>
