) -> DispatchResult
[src]
lock_id: LockIdentifier,
who: &AccountId,
amount: Self::Balance
) -> DispatchResult
Create a new balance lock on account who
.
If the new lock is valid (i.e. not already expired), it will push the
struct to the Locks
vec in storage. Note that you can lock more funds
than a user has.
If the lock lock_id
already exists, this will update it.
fn extend_lock(
lock_id: LockIdentifier,
who: &AccountId,
amount: Self::Balance
) -> DispatchResult
[src]
lock_id: LockIdentifier,
who: &AccountId,
amount: Self::Balance
) -> DispatchResult
Changes a balance lock (selected by lock_id
) so that it becomes less
liquid in all parameters or creates a new one if it does not exist.
Calling extend_lock
on an existing lock lock_id
differs from
set_lock
in that it applies the most severe constraints of the two,
while set_lock
replaces the lock with the new parameters. As in,
extend_lock
will set:
- maximum
amount
fn remove_lock(lock_id: LockIdentifier, who: &AccountId) -> DispatchResult
[src]
Remove an existing lock.
