struct, the main type that implements traits and standalone
functions within the pallet.
Implementations§
source§impl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub 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.
sourcepub 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.
sourcepub fn force_schedule_code_upgrade(
origin: OriginFor<T>,
para: ParaId,
new_code: ValidationCode,
relay_parent_number: BlockNumberFor<T>,
) -> DispatchResult
pub fn force_schedule_code_upgrade( origin: OriginFor<T>, para: ParaId, new_code: ValidationCode, relay_parent_number: BlockNumberFor<T>, ) -> DispatchResult
Schedule an upgrade as if it was scheduled in the given relay parent block.
sourcepub 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.
sourcepub fn force_queue_action(origin: OriginFor<T>, para: ParaId) -> DispatchResult
pub fn force_queue_action(origin: OriginFor<T>, para: ParaId) -> DispatchResult
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…
sourcepub fn add_trusted_validation_code(
origin: OriginFor<T>,
validation_code: ValidationCode,
) -> DispatchResult
pub fn add_trusted_validation_code( origin: OriginFor<T>, validation_code: ValidationCode, ) -> DispatchResult
Adds the validation code to the storage.
The code will not be added if it is already present. Additionally, if PVF pre-checking is running for that code, it will be instantly accepted.
Otherwise, the code will be added into the storage. Note that the code will be added
into storage with reference count 0. This is to account the fact that there are no users
for this code yet. The caller will have to make sure that this code eventually gets
used by some parachain or removed from the storage to avoid storage leaks. For the
latter prefer to use the poke_unused_validation_code
dispatchable to raw storage
manipulation.
This function is mainly meant to be used for upgrading parachains that do not follow the go-ahead signal while the PVF pre-checking feature is enabled.
sourcepub fn poke_unused_validation_code(
origin: OriginFor<T>,
validation_code_hash: ValidationCodeHash,
) -> DispatchResult
pub fn poke_unused_validation_code( origin: OriginFor<T>, validation_code_hash: ValidationCodeHash, ) -> DispatchResult
Remove the validation code from the storage iff the reference count is 0.
This is better than removing the storage directly, because it will not remove the code that was suddenly got used by some parachain while this dispatchable was pending dispatching.
sourcepub fn include_pvf_check_statement(
origin: OriginFor<T>,
stmt: PvfCheckStatement,
signature: ValidatorSignature,
) -> DispatchResultWithPostInfo
pub fn include_pvf_check_statement( origin: OriginFor<T>, stmt: PvfCheckStatement, signature: ValidatorSignature, ) -> DispatchResultWithPostInfo
Includes a statement for a PVF pre-checking vote. Potentially, finalizes the vote and enacts the results if that was the last vote before achieving the supermajority.
sourcepub fn force_set_most_recent_context(
origin: OriginFor<T>,
para: ParaId,
context: BlockNumberFor<T>,
) -> DispatchResult
pub fn force_set_most_recent_context( origin: OriginFor<T>, para: ParaId, context: BlockNumberFor<T>, ) -> DispatchResult
Set the storage for the current parachain head data immediately.

impl<T: Config> Pallet<T>
sourcepub fn sorted_para_heads() -> Vec<(u32, Vec<u8>)>
pub fn sorted_para_heads() -> Vec<(u32, Vec<u8>)>
Get a list of the first MAX_PARA_HEADS
para heads sorted by para_id.
This method is likely to be removed in the future.
sourcepub fn can_schedule_para_initialize(id: &ParaId) -> bool
pub fn can_schedule_para_initialize(id: &ParaId) -> bool
Verify that schedule_para_initialize
can be called successfully.
Returns false if para is already registered in the system.
sourcepub fn lifecycle(id: ParaId) -> Option<ParaLifecycle>
pub fn lifecycle(id: ParaId) -> Option<ParaLifecycle>
Returns the current lifecycle state of the para.
sourcepub fn is_valid_para(id: ParaId) -> bool
pub fn is_valid_para(id: ParaId) -> bool
Returns whether the given ID refers to a valid para.
Paras that are onboarding or offboarding are not included.
sourcepub fn is_offboarding(id: ParaId) -> bool
pub fn is_offboarding(id: ParaId) -> bool
Returns whether the given ID refers to a para that is offboarding.
An invalid or non-offboarding para ID will return false
.
sourcepub fn is_parachain(id: ParaId) -> bool
pub fn is_parachain(id: ParaId) -> bool
Whether a para ID corresponds to any live lease holding parachain.
Includes lease holding parachains which will downgrade to a on-demand parachains in the future.
sourcepub fn is_parathread(id: ParaId) -> bool
pub fn is_parathread(id: ParaId) -> bool
Whether a para ID corresponds to any live parathread (on-demand parachain).
Includes on-demand parachains which will upgrade to lease holding parachains in the future.
sourcepub fn test_on_new_session()
pub fn test_on_new_session()
Test function for triggering a new session in this pallet.
pub fn heads_insert(para_id: &ParaId, head_data: HeadData)
