Trait halo2_proofs::circuit::layouter::TableLayouter

pub trait TableLayouter<F: Field>: Debug {
    fn assign_cell<'v>(
        &'v mut self, 
        annotation: &'v (dyn Fn() -> String + 'v), 
        column: TableColumn, 
        offset: usize, 
        to: &'v mut (dyn FnMut() -> Result<Assigned<F>, Error> + 'v)
    ) -> Result<(), Error>;
}

Helper trait for implementing a custom Layouter.

This trait is used for implementing table assignments.

Required methods

fn assign_cell<'v>(
    &'v mut self,
    annotation: &'v (dyn Fn() -> String + 'v),
    column: TableColumn,
    offset: usize,
    to: &'v mut (dyn FnMut() -> Result<Assigned<F>, Error> + 'v)
) -> Result<(), Error>

Assigns a fixed value to a table cell.

Returns an error if the table cell has already been assigned to.
