pub struct StakingPagedQueryApi<'api> { /* private fields */ }

Implementations

impl<'api> StakingPagedQueryApi<'api>

pub fn bonded(&self) -> StoragePaged<AccountId, AccountId>

Map from all locked “stash” accounts to the controller account.

pub fn ledger(&self) -> StoragePaged<AccountId, StakingLedger<AccountId, u128>>

Map from all (unlocked) “controller” accounts to the info regarding the staking.

pub fn payee(&self) -> StoragePaged<AccountId, RewardDestination<AccountId>>

Where the reward payment should be made. Keyed by stash.

pub fn validators(&self) -> StoragePaged<AccountId, ValidatorPrefs>

The map from (wannabe) validator stash key to the preferences of that validator.

pub fn nominators(&self) -> StoragePaged<AccountId, Nominations<AccountId>>

The map from nominator stash key to the set of stash keys of all validators to nominate.

pub fn eras_start_session_index(&self) -> StoragePaged<u32, u32>

The session index at which the era start for the last HISTORY_DEPTH eras.

Note: This tracks the starting session (i.e. session index when era start being active) for the eras in [CurrentEra - HISTORY_DEPTH, CurrentEra].

pub fn eras_stakers( &self, key_0: u32 ) -> StoragePaged<AccountId, Exposure<AccountId, u128>>

Exposure of validator at era.

This is keyed first 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.

pub fn eras_stakers_clipped( &self, key_0: u32 ) -> StoragePaged<AccountId, Exposure<AccountId, u128>>

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.

pub fn eras_validator_prefs( &self, key_0: u32 ) -> StoragePaged<AccountId, ValidatorPrefs>

Similar to ErasStakers, this holds the preferences of validators.

This is keyed first by the era index to allow bulk deletion and then the stash account.

Is it removed after HISTORY_DEPTH eras.

pub fn eras_validator_reward(&self) -> StoragePaged<u32, u128>

The total validator era payout for the last HISTORY_DEPTH eras.

Eras that haven’t finished yet or has been removed doesn’t have reward.

pub fn eras_reward_points( &self ) -> StoragePaged<u32, EraRewardPoints<AccountId>>

Rewards for the last HISTORY_DEPTH eras. If reward hasn’t been set or has been removed then 0 reward is returned.

pub fn eras_total_stake(&self) -> StoragePaged<u32, u128>

The total amount staked for the last HISTORY_DEPTH eras. If total hasn’t been set or has been removed then 0 stake is returned.

pub fn unapplied_slashes( &self ) -> StoragePaged<u32, Vec<UnappliedSlash<AccountId, u128>>>

All unapplied slashes that are queued for later.

pub fn validator_slash_in_era( &self, key_0: u32 ) -> StoragePaged<AccountId, (Perbill, u128)>

All slashing events on validators, mapped by era to the highest slash proportion and slash value of the era.

pub fn nominator_slash_in_era( &self, key_0: u32 ) -> StoragePaged<AccountId, u128>

All slashing events on nominators, mapped by era to the highest slash value of the era.

pub fn slashing_spans(&self) -> StoragePaged<AccountId, SlashingSpans>

Slashing spans for stash accounts.

pub fn span_slash(&self) -> StoragePaged<(AccountId, u32), SpanRecord<u128>>

Records information about the maximum slash of a stash within a slashing span, as well as how much reward has been paid out.

pub fn permissioned_identity( &self ) -> StoragePaged<IdentityId, PermissionedIdentityPrefs>

Entities that are allowed to run operator/validator nodes.

Trait Implementations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
