Struct RingContext Copy item path

impl<const R: usize> RingContext<R>

pub fn new_testing() -> Self

Build an dummy instance for testing purposes.

pub fn max_keyset_size(&self) -> usize

Get the keyset max size.

pub fn prover(&self, public_keys: &[Public], public_idx: usize) -> RingProver

Get ring prover for the key at index public_idx in the public_keys set.

pub fn verifier(&self, public_keys: &[Public]) -> RingVerifier

Get ring verifier for the public_keys set.

pub fn verifier_key(&self, public_keys: &[Public]) -> RingVerifierKey

Build RingVerifierKey for lazy RingVerifier construction.

pub fn verifier_no_context(verifier_key: RingVerifierKey) -> RingVerifier

Constructs a RingVerifier from a VerifierKey without a RingContext instance.

While this approach is computationally slightly less efficient than using a pre-constructed RingContext, as some parameters need to be computed on-the-fly, it is beneficial in memory or storage constrained environments. This avoids the need to retain the full RingContext for ring signature verification. Instead, the VerifierKey contains only the essential information needed to verify ring proofs.
