Struct kas::messages::Erased

impl Erased

pub fn new<V>(v: V) -> Erased
where V: Any + Debug,

Construct

pub fn is<T>(&self) -> bool
where T: 'static,

Returns true if the inner type is the same as T.

pub fn downcast<T>(self) -> Result<Box<T>, Box<dyn Any>>
where T: 'static,

Attempt to downcast self to a concrete type.

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: 'static,

Returns some reference to the inner value if it is of type T, or None if it isn’t.
