Struct syn::Signature

pub struct Signature {
    pub constness: Option<Const>,
    pub asyncness: Option<Async>,
    pub unsafety: Option<Unsafe>,
    pub abi: Option<Abi>,
    pub fn_token: Fn,
    pub ident: Ident,
    pub generics: Generics,
    pub paren_token: Paren,
    pub inputs: Punctuated<FnArg, Comma>,
    pub variadic: Option<Variadic>,
    pub output: ReturnType,
}

A function signature in a trait or implementation: unsafe fn initialize(&self).

This type is available only if Syn is built with the "full" feature.

Implementations

impl Signature

pub fn receiver(&self) -> Option<&FnArg>

A method’s self receiver, such as &self or self: Box<Self>.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Signature

impl Hash for Signature

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Parse for Signature

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

impl PartialEq<Signature> for Signature

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl ToTokens for Signature

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

Write self to the given TokenStream.

pub fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

pub fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.
