Trait Implementations§

Source§

impl<'a> Deref for BoxTokenStream<'a>

Source§

type Target = dyn TokenStream + 'a

The resulting type after dereferencing.
Source§

fn deref(&self) -> &<BoxTokenStream<'a> as Deref>::Target

Dereferences the value.
Source§

impl DerefMut for BoxTokenStream<'_>

Source§

fn deref_mut(&mut self) -> &mut <BoxTokenStream<'_> as Deref>::Target

Mutably dereferences the value.
Source§

impl TokenStream for BoxTokenStream<'_>

Source§

fn advance(&mut self) -> bool

Advance to the next token Read more
Source§

fn token(&self) -> &Token

Returns a reference to the current token.
Source§

fn token_mut(&mut self) -> &mut Token

Returns a mutable reference to the current token.
Source§

fn next(&mut self) -> Option<&Token>

Source§

impl<T> Downcast for T
where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
