示例1: safeDelete
// safeDelete is used to delete a value in an immutable ticket treap, returning
// the mutated, immutable treap given as a result. It first checks to see if
// the key exists in the treap. If it does not, it returns an error.
func safeDelete(t *tickettreap.Immutable, k tickettreap.Key) (*tickettreap.Immutable, error) {
if !t.Has(k) {
return nil, stakeRuleError(ErrMissingTicket, fmt.Sprintf("attempted to "+
"delete non-existing key %v from treap", chainhash.Hash(k)))
}
return t.Delete(k), nil
}示例2: safePut
// safePut is used to put a value into an immutable ticket treap, returning
// the mutated, immutable treap given as a result. It first checks to see if
// there is already this key in the treap. If there is, it returns an error.
// TODO This function could also check to make sure the states of the ticket
// treap value are valid.
func safePut(t *tickettreap.Immutable, k tickettreap.Key, v *tickettreap.Value) (*tickettreap.Immutable, error) {
if t.Has(k) {
return nil, stakeRuleError(ErrDuplicateTicket, fmt.Sprintf("attempted "+
"to insert duplicate key %v into treap", chainhash.Hash(k)))
}
return t.Put(k, v), nil
