Expand description

Implementations
pub fn historical_root<KArg>(k: KArg) -> Option<(T::Hash, ValidatorCount)> where
KArg: EncodeLike<SessionIndex>,
pub fn historical_root<KArg>(k: KArg) -> Option<(T::Hash, ValidatorCount)> where
KArg: EncodeLike<SessionIndex>,
Mapping from historical session indices to session-data root hash and validator count.
Prune historical stored session roots up to (but not including)
up_to
.
Trait Implementations
Returns the current storage version as supported by the pallet.
Returns the on-chain storage version of the pallet as stored in the storage.
The block is being finalized. Implement to have something happen.
This will be run when the block is being finalized (before on_finalize
).
Implement to have something happen using the remaining weight.
Will not fire if the remaining weight is 0.
Return the weight used, the hook will subtract it from current weight used
and pass the result to the next on_idle
hook if it exists. Read more
The block is being initialized. Implement to have something happen. Read more
Perform a module upgrade. Read more
Implementing this function on a module allows you to perform long-running tasks that make (by default) validators generate transactions that feed results of those long-running computations back on chain. Read more

type Proof = MembershipProof
type Proof = MembershipProof
The proof of membership itself.
type IdentificationTuple = IdentificationTuple<T>
type IdentificationTuple = IdentificationTuple<T>
The full identification of a key owner and the stash account.
Prove membership of a key owner in the current block-state. Read more
Check a proof of membership on-chain. Return Some
iff the proof is
valid and recent enough to check. Read more
This function is being called after every block import (when fully synced). Read more
The block is being finalized. Implement to have something happen. Read more
Something that should happen at genesis.
The block is being finalized.
Implement to have something happen in case there is leftover weight.
Check the passed remaining_weight
to make sure it is high enough to allow for
your pallet’s extra computation. Read more
