Struct VerifierSubCircuit 

Source 
pub struct VerifierSubCircuit<const MAX_NUM_PROOFS: usize> { /* private fields */ }
Expand description

The recursive verifier sub-circuit consists of multiple chips, grouped into modules.

This circuit supports child verifying keys with at most 256 AIRs. ProofShapeAir range-checks AIR-index gaps with an 8-bit lookup when enforcing sorted proof-shape rows.

This struct is stateful.
