impl Account

source

pub fn new(
    account_hash: AccountHash,

    account: AccountHash,
    named_keys: NamedKeys,
    main_purse: URef
) -> Self

An Account constructor with presets for associated_keys and action_thresholds.

An account created with this method is valid and can be used as the target of a transaction. It will be created with an AssociatedKeys with a Weight of 1, and a default ActionThresholds.

source

pub fn extract_access_rights(&self) -> ContextAccessRights

Extracts the access rights from the named keys and main purse of the account.

Appends named keys to an account’s named_keys field.

source

Returns named keys.

source

pub fn named_keys_mut(&mut self) -> &mut NamedKeys

Returns a mutable reference to named keys.

source
