Struct syn::Field

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

A field of a struct or enum variant.

Fields

attrs: Vec<Attribute>

vis: Visibility

mutability: FieldMutability

ident: Option<Ident>

Name of the field, if any.

Fields of tuple structs have no names.

colon_token: Option<Colon>

ty: Type

Implementations

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 Clone for Field

fn clone(&self) -> Self

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, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Field

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

where H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Field

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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,

Convert self directly into a TokenStream object.
