Struct polkadot_runtime_parachains::hrmp::pallet::Pallet[−][src]

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

The pallet implementing the on-chain logic.

Implementations

Initiate opening a channel from a parachain to a given recipient with given channel parameters.

  • proposed_max_capacity - specifies how many messages can be in the channel at once.
  • proposed_max_message_size - specifies the maximum size of the messages.

These numbers are a subject to the relay-chain configuration limits.

The channel can be opened only after the recipient confirms it and only on a session change.

Accept a pending open channel request from the given sender.

The channel will be opened only on the next session boundary.

Initiate unilateral closing of a channel. The origin must be either the sender or the recipient in the channel being closed.

The closure can only happen on a session change.

This extrinsic triggers the cleanup of all the HRMP storage items that a para may have. Normally this happens once per session, but this allows you to trigger the cleanup immediately for a specific parachain.

Origin must be Root.

Force process HRMP open channel requests.

If there are pending HRMP open channel requests, you can use this function process all of those requests immediately.

Force process HRMP close channel requests.

If there are pending HRMP close channel requests, you can use this function process all of those requests immediately.

This cancels a pending open channel request. It can be canceled be either of the sender or the recipient for that request. The origin must be either of those.

The cancellation happens immediately. It is not possible to cancel the request if it is already accepted.

Routines and getters related to HRMP.

Initiate opening a channel from a parachain to a given recipient with given channel parameters.

Basically the same as hrmp_init_open_channel but intendend for calling directly from other pallets rather than dispatched.

Accept a pending open channel request from the given sender.

Basically the same as hrmp_accept_open_channel but intendend for calling directly from other pallets rather than dispatched.

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
