Expand description

Defines a configuration for a flex gate chip describing the selector, and advice column values for the chip.

Fields

basic_gates: [Vec<BasicGateConfig<F>>; 3]

A Vec of BasicGateConfig that define gates for each halo2 phase.

constants: Vec<Column<Fixed>>

A Vec of [Fixed] [Column]s for allocating constant values.

num_advice: [usize; 3]

Number of advice columns for each halo2 phase.

max_rows: usize

Max number of rows in flex gate.

Implementations

Generates a new FlexGateConfig

Assumes num_advice is a Vec of length MAX_PHASE

  • meta: [ConstraintSystem] of the circuit
  • strategy: GateStrategy of the flex gate
  • num_advice: Number of [Advice] [Column]s in each phase
  • num_fixed: Number of [Fixed] [Column]s in each phase
  • circuit_degree: Degree that expresses the size of circuit (i.e., 2^circuit_degree is the number of rows in the circuit)
