#include <bppp.hpp>

Public Member Functions
Nonce	nonce () const
	Returns the x-only public nonce encoded in the first 32 signature bytes.
Scalar32	s () const
	Returns the 32-byte Schnorr s scalar encoded in the last 32 signature bytes.
Bytes	serialize () const
	Serializes this signature into its fixed-size wire format.

Static Public Member Functions
static Result< Signature >	deserialize (std::span< const unsigned char > serialized, purify_secp_context *secp_context)
	Parses a serialized BIP340 signature.
