Cumulus related core primitive types and traits.

Modules

Structs

  • AbridgedHostConfiguration
    Abridged version of HostConfiguration (from the Configuration parachains host runtime module) meant to be used by a parachain or PDK such as cumulus.
  • AbridgedHrmpChannel
    Abridged version of HrmpChannel (from the Hrmp parachains host runtime module) meant to be used by a parachain or PDK such as cumulus.
  • Ancestor
    A unit struct which can be converted into a MultiLocation of the inner parents value.
  • AncestorThen
    A unit struct which can be converted into a MultiLocation of the inner parents value and the inner interior.
  • ChannelInfo
    Information about an XCMP channel.
  • CollationInfo
    Information about a collation.
  • CollationInfoV1
    Information about a collation.
  • Digest
    Generic header digest.
  • InboundDownwardMessage
    A wrapped version of DownwardMessage. The difference is that it has attached the block number when the message was sent.
  • MultiAsset
    Either an amount of a single fungible asset, or a single well-identified non-fungible asset.
  • MultiAssets
    A Vec of MultiAssets.
  • MultiLocation
    A relative path between state-bearing consensus systems.
  • PalletInfo
  • ParaId
    Unique identifier of a parachain.
  • ParachainBlockData
    The parachain block that is created by a collator.
  • Parent
    A unit struct which can be converted into a MultiLocation of parents value 1.
  • ParentThen
    A tuple struct which can be converted into a MultiLocation of parents value 1 with the inner interior.
  • PersistedValidationData
    The validation data provides information about how to create the inputs for validation of a candidate. This information is derived from the chain state and will vary from para to para, although some fields may be the same for every para.
  • QueryResponseInfo
    Information regarding the composition of a query response.
  • ValidationParams
    Validation parameters for evaluating the parachain validity function.
  • Weight
  • Xcm
  • XcmContext
    Contextual data pertaining to a specific list of XCM instructions.

Enums

  • AssetId
    Classification of an asset being concrete or abstract.
  • AssetInstance
    A general identifier for an instance of a non-fungible asset class.
  • BodyId
    An identifier of a pluralistic body.
  • BodyPart
    A part of a pluralistic body.
  • ChannelStatus
    The status of a channel.
  • CumulusDigestItem
    Consensus header digests for Cumulus parachains.
  • DigestItem
    Digest item that is able to encode/decode ‘system’ digest items and provide opaque access to other items.
  • Fungibility
    Classification of whether an asset is fungible or not, along with a mandatory amount or instance.
  • Instruction
    Cross-Consensus Message: A message from one consensus system to another.
  • Junction
    A single item in a path to describe the relative location of a consensus system.
  • Junctions
    Non-parent junctions that can be constructed, up to the length of 8. This specific Junctions implementation uses a Rust enum in order to make pattern matching easier.
  • MaybeErrorCode
  • MessageSendError
    Error description of a message send failure.
  • MultiAssetFilter
    MultiAsset collection, defined either by a number of MultiAssets or a single wildcard.
  • NetworkId
    A global identifier of a data structure existing within consensus.
  • OriginKind
    Basically just the XCM (more general) version of ParachainDispatchOrigin.
  • Outcome
    Outcome of an XCM execution.
  • Response
    Response data to a query.
  • SendError
    Error result value when attempting to send an XCM message.
  • ServiceQuality
    The “quality of service” considerations for message sending.
  • WeightLimit
    An optional weight limit.
  • WildFungibility
    Classification of whether an asset is fungible or not.
  • WildMultiAsset
    A wildcard representing a set of assets.
  • XcmError
    Error codes used in XCM. The first errors codes have explicit indices and are part of the XCM format. Those trailing are merely part of the XCM implementation; there is no expectation that they will retain the same index over time.
  • XcmpMessageFormat
    The aggregate XCMP message format.

Constants

Traits

Functions

  • extract_relay_parent
    Extract the relay-parent from the provided header digest. Returns None if none were found.
  • send_xcm
    Convenience function for using a SendXcm implementation. Just interprets the dest and wraps both in Some before passing them as as mutable references into T::send_xcm.
  • validate_send
    Convenience function for using a SendXcm implementation. Just interprets the dest and wraps both in Some before passing them as as mutable references into T::send_xcm.
