Struct polkadot_runtime_common::paras_registrar::pallet::Pallet[−][src]

pub struct Pallet<T>(_);
Expand description

The pallet implementing the on-chain logic.

Implementations

Register head data and validation code for a reserved Para Id.

Arguments
  • origin: Must be called by a Signed origin.
  • id: The para ID. Must be owned/managed by the origin signing account.
  • genesis_head: The genesis head data of the parachain/thread.
  • validation_code: The initial validation code of the parachain/thread.
Deposits/Fees

The origin signed account must reserve a corresponding deposit for the registration. Anything already reserved previously for this para ID is accounted for.

Events

The Registered event is emitted in case of success.

Force the registration of a Para Id on the relay chain.

This function must be called by a Root origin.

The deposit taken can be specified for this registration. Any ParaId can be registered, including sub-1000 IDs which are System Parachains.

Deregister a Para Id, freeing all data and returning any deposit.

The caller must be Root, the para owner, or the para itself. The para must be a parathread.

Swap a parachain with another parachain or parathread.

The origin must be Root, the para owner, or the para itself.

The swap will happen only if there is already an opposite swap pending. If there is not, the swap will be stored in the pending swaps map, ready for a later confirmatory swap.

The ParaIds remain mapped to the same head data and code so external code can rely on ParaId to be a long-term identifier of a notional “parachain”. However, their scheduling info (i.e. whether they’re a parathread or parachain), auction information and the auction deposit are switched.

Remove a manager lock from a para. This will allow the manager of a previously locked para to deregister or swap a para without using governance.

Can only be called by the Root origin.

Reserve a Para Id on the relay chain.

This function will reserve a new Para Id to be owned/managed by the origin account. The origin account is able to register head data and validation code using register to create a parathread. Using the Slots pallet, a parathread can then be upgraded to get a parachain slot.

Arguments
  • origin: Must be called by a Signed origin. Becomes the manager/owner of the new para ID.
Deposits/Fees

The origin must reserve a deposit of ParaDeposit for the registration.

Events

The Reserved event is emitted in case of success, which provides the ID reserved for use.

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

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

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

Return the manager AccountId of a para if one exists.

The account ID type that encodes a parachain manager ID.

All parachains. Ordered ascending by ParaId. Parathreads are not included.

Return if a ParaId is a Parathread.

Return if a ParaId is a Parachain.

Apply a lock to the para registration so that it cannot be modified by the manager directly. Instead the para must use its sovereign governance or the governance of the relay chain. Read more

Remove any lock on the para registration.

Register a Para ID under control of who. Registration may be be delayed by session rotation. Read more

Deregister a Para ID, free any data, and return any deposits.

Elevate a para to parachain status.

Lower a para back to normal from parachain status.

Execute any pending state transitions for paras. For example onboarding to parathread, or parathread to parachain. Read more

Return if a ParaId is registered in the system.
