Opaque data structure that holds a parsed and valid "xonly" public key.
An xonly pubkey encodes a point whose Y coordinate is even. It is serialized using only its X coordinate (32 bytes). See BIP340 for more information about xonly pubkeys.
The exact representation of data inside is implementation defined and not guaranteed to be portable between different platforms or versions. It is however guaranteed to be 64 bytes in size, and can be safely copied/moved. If you need to convert to a format suitable for storage, transmission, use use secp256k1_xonly_pubkey_serialize and secp256k1_xonly_pubkey_parse. To compare keys, use secp256k1_xonly_pubkey_cmp.
