Struct syn::FnDecl

pub struct FnDecl {
    pub fn_token: Fn,
    pub generics: Generics,
    pub paren_token: Paren,
    pub inputs: Punctuated<FnArg, Comma>,
    pub variadic: Option<Dot3>,
    pub output: ReturnType,
}

Header of a function declaration, without including the body.

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

Trait Implementations

impl Eq for FnDecl

impl PartialEq<FnDecl> for FnDecl

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

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

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

This method tests for !=.

impl Clone for FnDecl

fn clone(&self) -> FnDecl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FnDecl

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

Formats the value using the given formatter.

impl Hash for FnDecl

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].
