Struct syn::Field

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

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

Methods

impl Field

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

Parses a named (braced struct) field.

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

Parses an unnamed (tuple struct) field.

Trait Implementations

impl Eq for Field

impl PartialEq<Field> for Field

fn eq(&self, other: &Field) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Field) -> bool

This method tests for !=.

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Field

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Field

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl ToTokens for Field

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

Write self to the given TokenStream.

fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.
