Module Functions​

pub derive_address​

Given an ID and a Key, it calculates the derived address.

public fun derive_address<K: copy, drop, store>(parent: iota::object::ID, key: K): address
Implementation
public fun derive_address<K: copy + drop + store>(parent: ID, key: K): address {
    iota::dynamic_field::hash_type_and_key(parent.to_address(), DerivedObjectKey(key))
}

Structs​

struct DerivedObjectKey​

An internal key to protect from generating the same UID twice (e.g. collide with DFs)

public struct DerivedObjectKey<K: copy, drop, store> has copy, drop, store
Fields
0: K
