for<'v> Assigned<F>: From<&'v V>,
sourcepub fn value_field(&self) -> Value<Assigned<F>>
pub fn value_field(&self) -> Value<Assigned<F>>
Returns the field element value of the AssignedCell
.
sourceimpl<F: Field> AssignedCell<Assigned<F>, F>
impl<F: Field> AssignedCell<Assigned<F>, F>
sourcepub fn evaluate(self) -> AssignedCell<F, F>
pub fn evaluate(self) -> AssignedCell<F, F>
Evaluates this assigned cell’s value directly, performing an unbatched inversion if necessary.
If the denominator is zero, the returned cell’s value is zero.

AR: Into<String>,
pub fn copy_advice<A, AR>(
&self,
annotation: A,
region: &mut Region<'_, F>,
column: Column<Advice>,
offset: usize
) -> Result<Self, Error> where
A: Fn() -> AR,
AR: Into<String>,
Copies the value to a given advice cell and constrains them to be equal.
Returns an error if either this cell or the given cell are in columns where equality has not been enabled.
