signer - [mainnet]

Functions

borrow_address

signer is a builtin move type that represents an address that has been verfied by the VM.

VM Runtime representation is equivalent to following:

enum signer has drop {
Master { account: address },
Permissioned { account: address, permissions_address: address },
}

for bcs serialization:

struct signer has drop {
account: address,
}

^ The discrepency is needed to maintain backwards compatibility of signer serialization semantics.

borrow_address borrows this inner field

address_of

public fun address_of(s: &signer): address

public fun address_of(s: &signer): address {
    *borrow_address(s)
}
