Trait Implementations

impl Clone for Extern

Available on crate feature clone-impls only.

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Extern

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl Default for Extern

fn default() -> Self

Returns the “default value” for a type.

impl From<Extern> for Ident

fn from(token: Extern) -> Ident

Converts to this type from the input type.

impl Hash for Extern

Available on crate feature extra-traits only.

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 Parse for Extern

Available on crate feature parsing only.

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

impl PartialEq<Extern> for Extern

Available on crate feature extra-traits only.

fn eq(&self, _other: &Extern) -> bool

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

const 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 Extern

Available on crate feature printing only.

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

Convert self directly into a TokenStream object.

impl Copy for Extern

Available on crate feature clone-impls only.

impl Eq for Extern

Available on crate feature extra-traits only.

impl Token for Extern
