Required Methods

fn eval( &mut self, session: &mut SessionState, op: &(dyn Op + 'static), inputs: SmallVec<[TValue; 4]> ) -> Result<SmallVec<[TValue; 4]>, Error>

Implementations

impl dyn OpState + 'static

pub fn is<__T>(&self) -> boolwhere __T: OpState,

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

pub fn downcast<__T>( self: Box<dyn OpState + 'static, Global> ) -> Result<Box<__T, Global>, Box<dyn OpState + 'static, Global>>where __T: OpState,

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 OpState + 'static> ) -> Result<Rc<__T>, Rc<dyn OpState + 'static>>where __T: OpState,

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: OpState,

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: OpState,

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