Implementations

impl dyn State

pub fn is<__T>(&self) -> bool

where __T: State,

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T>(self: Box<dyn State>) -> Result<Box<__T>, Box<dyn State>>

where __T: State,

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T>(self: Rc<dyn State>) -> Result<Rc<__T>, Rc<dyn State>>

where __T: State,

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T>(&self) -> Option<&__T>

where __T: State,

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>

where __T: State,

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
