pub fn reap_stash<T: Config>(stash: T::AccountId, num_slashing_spans: u32)Expand description
Remove all data structures concerning a staker/stash once it is at a state where it can
be considered dust in the staking system. The requirements are:
- the 
total_balanceof the stash is below existential deposit. - or, the 
ledger.totalof the stash is below existential deposit. - or, existential deposit is zero and either 
total_balanceorledger.totalis zero. 
The former can happen in cases like a slash; the latter when a fully unbonded account
is still receiving staking rewards in RewardDestination::Staked.
It can be called by anyone, as long as stash meets the above requirements.
Refunds the transaction fees upon successful execution.
