Struct pallet_curveless_staking::ErasStakersClipped [−][src]
Clipped Exposure of validator at era.
This is similar to ErasStakers but number of nominators exposed is reduced to the
T::MaxNominatorRewardedPerValidator biggest stakers.
(Note: the field total and own of the exposure remains unchanged).
This is used to limit the i/o cost for the nominator payout.
This is keyed fist by the era index to allow bulk deletion and then the stash account.
Is it removed after HISTORY_DEPTH eras.
If stakers hasn’t been set or has been removed then empty exposure is returned.
