}

Required Methods

fn check_older(&self, locktime: u32) -> Option<bool>

CheckOlder checks if the OP_CHECKSEQUENCEVERIFY call is satisfied in the context of a transaction.

fn check_after(&self, locktime: u32) -> Option<bool>

CheckAfter checks if the OP_CHECKLOCKTIMEVERIFY call is satisfied in the context of a transaction.

fn sign(&self, pubkey: &KeyToken) -> Option<(Vec<u8>, bool)>

Sign generates a signature for the given public key.

fn preimage(&self, hash_func: HashFunc, hash: &[u8]) -> Option<(Vec<u8>, bool)>

Preimage returns the preimage of the hash value. hashFunc is one of “sha256”, “ripemd160”, “hash256”, “hash160”.
