Struct polkadot_runtime_common::slots::pallet::Pallet [−][src]
pub struct Pallet<T>(_);Expand description
The pallet implementing the on-chain logic.
Implementations
pub fn force_lease(
origin: OriginFor<T>,
para: ParaId,
leaser: T::AccountId,
amount: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance,
period_begin: <T as Config>::BlockNumber,
period_count: <T as Config>::BlockNumber
) -> DispatchResult
pub fn force_lease(
origin: OriginFor<T>,
para: ParaId,
leaser: T::AccountId,
amount: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance,
period_begin: <T as Config>::BlockNumber,
period_count: <T as Config>::BlockNumber
) -> DispatchResult
Just a connect into the lease_out call, in case Root wants to force some lease to happen
independently of any other on-chain mechanism to use it.
Can only be called by the Root origin.
Clear all leases for a Para Id, refunding any deposits back to the original owners.
Can only be called by the Root origin.
Try to onboard a parachain that has a lease for the current lease period.
This function can be useful if there was some state issue with a para that should have onboarded, but was unable to. As long as they have a lease period, we can let them onboard from here.
Origin must be signed, but can be called by anyone.
Amounts held on deposit for each (possibly future) leased parachain.
The actual amount locked on its behalf by any account at any time is the maximum of the second values of the items in this list whose first value is the account.
The first item in the list is the amount locked for the current Lease Period. Following items are for the subsequent lease periods.
The default value (an empty list) implies that the parachain no longer exists (or never existed) as far as this pallet is concerned.
If a parachain doesn’t exist yet but is scheduled to exist in the future, then it
will be left-padded with one or more Nones to denote the fact that nothing is held on
deposit for the non-existent chain currently, but is held at some point in the future.
It is illegal for a None value to trail in the list.
Trait Implementations
Get the benchmarks available for this pallet. Generally there is one benchmark per extrinsic, so these are sometimes just called “extrinsics”. Read more
fn run_benchmark(
extrinsic: &[u8],
c: &[(BenchmarkParameter, u32)],
whitelist: &[TrackedStorageKey],
verify: bool,
internal_repeats: u32
) -> Result<Vec<BenchmarkResult>, BenchmarkError>
fn run_benchmark(
extrinsic: &[u8],
c: &[(BenchmarkParameter, u32)],
whitelist: &[TrackedStorageKey],
verify: bool,
internal_repeats: u32
) -> Result<Vec<BenchmarkResult>, BenchmarkError>
Run the benchmarks for this pallet.
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 initialized. Implement to have something happen. Read more
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
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 LeasePeriod = T::BlockNumber
type LeasePeriod = T::BlockNumber
The measurement type for counting lease periods (generally just a BlockNumber).
fn lease_out(
para: ParaId,
leaser: &Self::AccountId,
amount: <Self::Currency as Currency<Self::AccountId>>::Balance,
period_begin: Self::LeasePeriod,
period_count: Self::LeasePeriod
) -> Result<(), LeaseError>
fn lease_out(
para: ParaId,
leaser: &Self::AccountId,
amount: <Self::Currency as Currency<Self::AccountId>>::Balance,
period_begin: Self::LeasePeriod,
period_count: Self::LeasePeriod
) -> Result<(), LeaseError>
Lease a new parachain slot for para. Read more
Return the amount of balance currently held in reserve on leaser’s account for leasing para. This won’t
go down outside a lease period. Read more
The length of a lease period, and any offset which may be introduced. This is only used in benchmarking to automate certain calls. Read more
Returns the lease period at block, and if this is the first block of a new lease period. Read more
fn already_leased(
para_id: ParaId,
first_period: Self::LeasePeriod,
last_period: Self::LeasePeriod
) -> bool
fn already_leased(
para_id: ParaId,
first_period: Self::LeasePeriod,
last_period: Self::LeasePeriod
) -> bool
Returns true if the parachain already has a lease in any of lease periods in the inclusive
range [first_period, last_period], intersected with the unbounded range [current_lease_period..] . 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
