Expand description

Abridged version of HostConfiguration (from the Configuration parachains host runtime module) meant to be used by a parachain or PDK such as cumulus.

Fields§

§max_code_size: u32

The maximum validation code size, in bytes.

§max_head_data_size: u32

The maximum head-data size, in bytes.

§max_upward_queue_count: u32

Total number of individual messages allowed in the parachain -> relay-chain message queue.

§max_upward_queue_size: u32

Total size of messages allowed in the parachain -> relay-chain message queue before which no further messages may be added to it. If it exceeds this then the queue may contain only a single message.

§max_upward_message_size: u32

The maximum size of an upward message that can be sent by a candidate.

This parameter affects the size upper bound of the CandidateCommitments.

§max_upward_message_num_per_candidate: u32

The maximum number of messages that a candidate can contain.

This parameter affects the size upper bound of the CandidateCommitments.

§hrmp_max_message_num_per_candidate: u32

The maximum number of outbound HRMP messages can be sent by a candidate.

This parameter affects the upper bound of size of CandidateCommitments.

§validation_upgrade_cooldown: u32

The minimum period, in blocks, between which parachains can update their validation code.

§validation_upgrade_delay: u32

The delay, in blocks, before a validation upgrade is applied.
