Expand description
Abridged version of HrmpChannel
(from the Hrmp
parachains host runtime module) meant to be
used by a parachain or PDK such as cumulus.
Fields§
§max_capacity: u32
The maximum number of messages that can be pending in the channel at once.
max_total_size: u32
The maximum total size of the messages that can be pending in the channel at once.
max_message_size: u32
The maximum message size that could be put into the channel.
msg_count: u32
The current number of messages pending in the channel.
Invariant: should be less or equal to max_capacity
.s`.
total_size: u32
The total size in bytes of all message payloads in the channel.
Invariant: should be less or equal to max_total_size
.
mqc_head: Option<Hash>
A head of the Message Queue Chain for this channel. Each link in this chain has a form:
(prev_head, B, H(M))
, where
prev_head
: is the previous value ofmqc_head
or zero if none.B
: is the [relay-chain] block number in which a message was appendedH(M)
: is the hash of the message being appended. This value is initialized to a special value that consists of all zeroes which indicates that no messages were previously added.
