Type Alias LookupInput 

pub type LookupInput<F> = (Vec<SymbolicExpression<F>>, SymbolicExpression<F>, Direction);

A type alias for a lookup input tuple.

The tuple contains:

• a vector of symbolic expressions representing the elements involved in the lookup,
• a symbolic expression representing the multiplicity of the lookup,
• a direction indicating whether the elements are being sent or received.

Example

use p3_lookup::{LookupInput, Direction};
use p3_air::SymbolicExpression;

let lookup_input: LookupInput<SymbolicExpression<F>> = (
    vec![SymbolicExpression::Constant(F::ONE)],
    SymbolicExpression::Constant(F::ONE),
    Direction::Send
);
