as_dict function for hashes

[crosschainer]

This is the example contract:

balances = Hash(default_value=0)

@construct
def seed(vk: str):
    balances['boi'] = 111_111_111
    balances['bob'] = 100_000
    balances['bob', 'down'] = 100_000

@export
def holders():
    return balances.as_dict()

When calling holders()

It will return a dict copy {'boi': 111111111, 'bob': 100000}

which then can be looped through. for example for airdrops
