Implementations
pub fn force_set_current_code(
origin: OriginFor<T>,
para: ParaId,
new_code: ValidationCode
) -> DispatchResult
pub fn force_set_current_code(
origin: OriginFor<T>,
para: ParaId,
new_code: ValidationCode
) -> DispatchResult
Set the storage for the parachain validation code immediately.
pub fn force_set_current_head(
origin: OriginFor<T>,
para: ParaId,
new_head: HeadData
) -> DispatchResult
pub fn force_set_current_head(
origin: OriginFor<T>,
para: ParaId,
new_head: HeadData
) -> DispatchResult
Set the storage for the current parachain head data immediately.
pub fn force_schedule_code_upgrade(
origin: OriginFor<T>,
para: ParaId,
new_code: ValidationCode,
relay_parent_number: T::BlockNumber
) -> DispatchResult
pub fn force_schedule_code_upgrade(
origin: OriginFor<T>,
para: ParaId,
new_code: ValidationCode,
relay_parent_number: T::BlockNumber
) -> DispatchResult
Schedule an upgrade as if it was scheduled in the given relay parent block.
pub fn force_note_new_head(
origin: OriginFor<T>,
para: ParaId,
new_head: HeadData
) -> DispatchResult
pub fn force_note_new_head(
origin: OriginFor<T>,
para: ParaId,
new_head: HeadData
) -> DispatchResult
Note a new block head for para within the context of the current block.
Put a parachain directly into the next session’s action queue. We can’t queue it any sooner than this without going into the initializer…
All parachains. Ordered ascending by ParaId. Parathreads are not included.
pub fn current_code_hash<KArg>(k: KArg) -> Option<ValidationCodeHash> where
KArg: EncodeLike<ParaId>,
pub fn current_code_hash<KArg>(k: KArg) -> Option<ValidationCodeHash> where
KArg: EncodeLike<ParaId>,
The validation code hash of every live para.
Corresponding code can be retrieved with [CodeByHash].
pub fn past_code_meta<KArg>(k: KArg) -> ParaPastCodeMeta<T::BlockNumber> where
KArg: EncodeLike<ParaId>,
pub fn past_code_meta<KArg>(k: KArg) -> ParaPastCodeMeta<T::BlockNumber> where
KArg: EncodeLike<ParaId>,
Past code of parachains. The parachains themselves may not be registered anymore, but we also keep their code on-chain for the same amount of time as outdated code to keep it available for secondary checkers.
pub fn future_code_upgrade_at<KArg>(k: KArg) -> Option<T::BlockNumber> where
KArg: EncodeLike<ParaId>,
pub fn future_code_upgrade_at<KArg>(k: KArg) -> Option<T::BlockNumber> where
KArg: EncodeLike<ParaId>,
The block number at which the planned code change is expected for a para.
The change will be applied after the first parablock for this ID included which executes
in the context of a relay chain block with a number >= expected_at.
The actions to perform during the start of a specific session index.
pub fn code_by_hash<KArg>(k: KArg) -> Option<ValidationCode> where
KArg: EncodeLike<ValidationCodeHash>,
pub fn code_by_hash<KArg>(k: KArg) -> Option<ValidationCode> where
KArg: EncodeLike<ValidationCodeHash>,
Validation code stored by its hash.
This storage is consistent with [FutureCodeHash], [CurrentCodeHash] and
[PastCodeHash].
Verify that schedule_para_initialize can be called successfully.
Returns false if para is already registered in the system.
Returns the current lifecycle state of the para.
Returns whether the given ID refers to a valid para.
Paras that are onboarding or offboarding are not included.
Whether a para ID corresponds to any live parachain.
Includes parachains which will downgrade to a parathread in the future.
Whether a para ID corresponds to any live parathread.
Includes parathreads which will upgrade to parachains in the future.
Test function for triggering a new session in this pallet.
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 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

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
