pub fn type_id(&self) -> TypeId

Gets the TypeId of the parameter.

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: Any,

pub fn is<T>(&self) -> bool
where T: Any,

Returns true if the parameter type is T.

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

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

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.
