Struct Field

pub struct Field {
    pub attrs: Vec<Attribute>,
    pub vis: Visibility,
    pub ident: Option<Ident>,
    pub colon_token: Option<Colon>,
    pub ty: Type,
    pub assign: Option<(Eq, Expr)>,
}

A field of a struct or enum variant.

This is a variant of syn::Field supporting field initializers.

Fields

attrs: Vec<Attribute>

Attributes tagged on the field.

vis: Visibility

Visibility of the field.

ident: Option<Ident>

Name of the field, if any.

colon_token: Option<Colon>

: token before type

ty: Type

Type of the field.

assign: Option<(Eq, Expr)>

Optional field initializer.

This is considered legal input when parsing, but not legal output. An attribute rule such as AttrImplDefault must remove the initializer before output is generated.

Implementations

impl Field

pub fn parse_named(input: ParseStream<'_>) -> Result<Self>

Parse a named field

pub fn parse_unnamed(input: ParseStream<'_>) -> Result<Self>

Parse an unnamed field

impl ToTokens for Field

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,
