) -> Self
sourcepub fn set_preimage(&mut self, preimage: &[F])
pub fn set_preimage(&mut self, preimage: &[F])
Replace the elements with the provided optional items.
Panics
Panics if the provided slice is bigger than the arity.
sourcepub fn input(&mut self, element: F) -> Result<usize, Error>
pub fn input(&mut self, element: F) -> Result<usize, Error>
The returned usize
represents the element position (within arity) for the input operation
