Expand description
Constraints on the actions that can be taken by a new parachain block. These limitations are implicitly associated with some particular parachain, which should be apparent from usage.
Fields§
§min_relay_parent_number: N
The minimum relay-parent number accepted under these constraints.
max_pov_size: u32
The maximum Proof-of-Validity size allowed, in bytes.
max_code_size: u32
The maximum new validation code size allowed, in bytes.
ump_remaining: u32
The amount of UMP messages remaining.
ump_remaining_bytes: u32
The amount of UMP bytes remaining.
max_ump_num_per_candidate: u32
The maximum number of UMP messages allowed per candidate.
dmp_remaining_messages: Vec<N>
Remaining DMP queue. Only includes sent-at block numbers.
hrmp_inbound: InboundHrmpLimitations<N>
The limitations of all registered inbound HRMP channels.
hrmp_channels_out: Vec<(Id, OutboundHrmpChannelLimitations)>
The limitations of all registered outbound HRMP channels.
max_hrmp_num_per_candidate: u32
The maximum number of HRMP messages allowed per candidate.
required_parent: HeadData
The required parent head-data of the parachain.
validation_code_hash: ValidationCodeHash
The expected validation-code-hash of this parachain.
upgrade_restriction: Option<UpgradeRestriction>
The code upgrade restriction signal as-of this parachain.
future_validation_code: Option<(N, ValidationCodeHash)>
The future validation code hash, if any, and at what relay-parent number the upgrade would be minimally applied.
