Events¶
BatchChecked¶
A batch was partially checked for the given eras, but the process did not finish.
Attributes¶
| Name | Type | Composition |
|---|---|---|
| eras | Vec<EraIndex> |
['u32'] |
BatchFinished¶
A batch of a given size was terminated.
This is always follows by a number of Unstaked or Slashed events, marking the end
of the batch. A new batch will be created upon next block.
Attributes¶
| Name | Type | Composition |
|---|---|---|
| size | u32 |
u32 |
InternalError¶
An internal error happened. Operations will be paused now.
Attributes¶
No attributes
Slashed¶
A staker was slashed for requesting fast-unstake whilst being exposed.
Attributes¶
| Name | Type | Composition |
|---|---|---|
| stash | T::AccountId |
AccountId |
| amount | BalanceOf<T> |
u128 |
Unstaked¶
A staker was unstaked.

{'Ok': (), 'Err': {'Other': None, 'CannotLookup': None, 'BadOrigin': None, 'Module': {'index': 'u8', 'error': '[u8; 4]'}, 'ConsumerRemaining': None, 'NoProviders': None, 'TooManyConsumers': None, 'Token': ('FundsUnavailable', 'OnlyProvider', 'BelowMinimum', 'CannotCreate', 'UnknownAsset', 'Frozen', 'Unsupported', 'CannotCreateHold', 'NotExpendable', 'Blocked'), 'Arithmetic': ('Underflow', 'Overflow', 'DivisionByZero'), 'Transactional': ('LimitReached', 'NoLayer'), 'Exhausted': None, 'Corruption': None, 'Unavailable': None, 'RootNotAllowed': None}} |
Storage functions¶
CounterForQueue¶
Counter for the related counted storage map
Python¶
result = substrate.query(
'FastUnstake', 'CounterForQueue', []
)
Return value¶
'u32'
ErasToCheckPerBlock¶
Number of eras to check per block.
If set to 0, this pallet does absolutely nothing. Cannot be set to more than
[Config::MaxErasToCheckPerBlock].
Based on the amount of weight available at [Pallet::on_idle], up to this many eras are
checked. The checking is represented by updating [UnstakeRequest::checked], which is
stored in [Head].
Python¶
result = substrate.query(
'FastUnstake', 'ErasToCheckPerBlock', []
)
Return value¶
'u32'
Head¶
The current "head of the queue" being unstaked.
The head in itself can be a batch of up to [Config::BatchSize] stakers.
Python¶
result = substrate.query(
'FastUnstake', 'Head', []
)
Return value¶
{'checked': ['u32'], 'stashes': [('AccountId', 'u128')]}
Queue¶
The map of all accounts wishing to be unstaked.
Keeps track of AccountId wishing to unstake and it's corresponding deposit.
Python¶
result = substrate.query(
'FastUnstake', 'Queue', ['AccountId']
)
Return value¶
'u128'
Constants¶
Deposit¶
Deposit to take for unstaking, to make sure we're able to slash the it in order to cover the costs of resources on unsuccessful unstake.
Value¶
10000000000
Python¶
constant = substrate.get_constant('FastUnstake', 'Deposit')
Errors¶
AlreadyHead¶
The provided un-staker is already in Head, and cannot deregister.
AlreadyQueued¶
The bonded account has already been queued.
CallNotAllowed¶
The call is not allowed at this point because the pallet is not active.
NotController¶
The provided Controller account was not found.
This means that the given account is not bonded.
NotFullyBonded¶
The bonded account has active unlocking chunks.
NotQueued¶
The provided un-staker is not in the Queue.
