Contains one variant per dispatchable that can be called by an extrinsic.

Variants

hrmp_init_open_channel

Fields

recipient: ParaId

proposed_max_capacity: u32

proposed_max_message_size: u32

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.

hrmp_accept_open_channel

Fields

sender: ParaId

Accept a pending open channel request from the given sender.

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

hrmp_close_channel

Fields

channel_id: HrmpChannelId

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.

force_clean_hrmp

Fields

para: ParaId

inbound: u32

outbound: u32

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.

Number of inbound and outbound channels for para must be provided as witness data of weighing.

force_process_hrmp_open

Fields

channels: u32

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.

Total number of opening channels must be provided as witness data of weighing.

force_process_hrmp_close

Fields

channels: u32

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.

Total number of closing channels must be provided as witness data of weighing.

hrmp_cancel_open_request

Fields

channel_id: HrmpChannelId

open_requests: u32

This cancels a pending open channel request. It can be canceled by 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.

Total number of open requests (i.e. HrmpOpenChannelRequestsList) must be provided as witness data.

Trait Implementations

impl<T: Config> Clone for Call<T>

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>
