Implementations
pub fn new(
account_hash: AccountHash,
named_keys: NamedKeys,
main_purse: URef,
associated_keys: AssociatedKeys,
action_thresholds: ActionThresholds
) -> Self
pub fn new(
account_hash: AccountHash,
named_keys: NamedKeys,
main_purse: URef,
associated_keys: AssociatedKeys,
action_thresholds: ActionThresholds
) -> Self
Creates a new account.
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
.
Extracts the access rights from the named keys and main purse of the account.
Appends named keys to an account’s named_keys field.
Returns named keys.
Returns a mutable reference to named keys.
Returns account hash.
Returns main purse.
Returns an AccessRights::ADD
-only version of the main purse’s URef
.
Returns associated keys.
Returns action thresholds.
pub fn add_associated_key(
&mut self,
account_hash: AccountHash,
weight: Weight
) -> Result<(), AddKeyFailure>
pub fn add_associated_key(
&mut self,
account_hash: AccountHash,
weight: Weight
) -> Result<(), AddKeyFailure>
Adds an associated key to an account.
pub fn remove_associated_key(
&mut self,
account_hash: AccountHash
) -> Result<(), RemoveKeyFailure>
pub fn remove_associated_key(
&mut self,
account_hash: AccountHash
) -> Result<(), RemoveKeyFailure>
Removes an associated key from an account.
Verifies that removing the key will not cause the remaining weight to fall below any action thresholds.
pub fn update_associated_key(
&mut self,
account_hash: AccountHash,
weight: Weight
) -> Result<(), UpdateKeyFailure>
pub fn update_associated_key(
&mut self,
account_hash: AccountHash,
weight: Weight
) -> Result<(), UpdateKeyFailure>
Updates an associated key.
Returns an error if the update would result in a violation of the key management thresholds.
pub fn set_action_threshold(
&mut self,
action_type: ActionType,
weight: Weight
) -> Result<(), SetThresholdFailure>
pub fn set_action_threshold(
&mut self,
action_type: ActionType,
weight: Weight
) -> Result<(), SetThresholdFailure>
Sets new action threshold for a given action type for the account.
Returns an error if the new action threshold weight is greater than the total weight of the account’s associated keys.
Verifies if user can set action threshold.
Checks whether all authorization keys are associated with this account.
Checks whether the sum of the weights of all authorization keys is greater or equal to deploy threshold.
Checks whether the sum of the weights of all authorization keys is greater or equal to key management threshold.
Trait Implementations
Performs the conversion.
Returns the length of the Vec<u8>
which would be returned from a successful call to
to_bytes()
or into_bytes()
. The data is not actually serialized, so this call is
relatively cheap. Read more
type Error = TypeMismatch
type Error = TypeMismatch
The type returned in the event of a conversion error.
