If possible give a hint of expected size of the encoding. Read more
source§fn encode_to<T>(&self, dest: &mut T)where
    T: Output + ?Sized,
 
fn encode_to<T>(&self, dest: &mut T)where
    T: Output + ?Sized,
Convert self to a slice and append it to the destination.

§fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
 
fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
Convert 
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
 
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
Convert 
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more§fn as_any(&self) -> &(dyn Any + 'static)
 
fn as_any(&self) -> &(dyn Any + 'static)
Convert 
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s. Read more§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
 
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert 
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s. Read moresource§impl<Q, K> Equivalent<K> for Qwhere
