Modules

• dmp
  To prevent Out of Memory errors on the DownwardMessageQueue, an exponential fee factor (DeliveryFeeFactor) is set. The fee factor increments exponentially after the number of messages in the DownwardMessageQueue passes a threshold. This threshold is set as:
• hrmp

Macros

• assert_expected_events
• assert_ok
  Panic if an expression doesn’t evaluate to Ok.
• bx

Structs

• AccountId32
  An opaque 32-byte cryptographic identifier.
• Asset
  Either an amount of a single fungible asset, or a single well-identified non-fungible asset.
• BridgeHubMessageHandler
• BridgeMessage
• BridgeMessageDispatchError
• BridgeMessagesInstance1
  Instance1 to be used for instantiable pallets defined with the #[pallet] macro. Instances 2-16 are also available but are hidden from docs.
• DoubleEncoded
  Wrapper around the encoded and decoded versions of a value. Caches the decoded value once computed.
• HrmpChannelId
  A type that uniquely identifies an HRMP channel. An HRMP channel is established between two paras. In text, we use the notation (A, B) to specify a channel between A and B. The channels are unidirectional, meaning that (A, B) and (B, A) refer to different channels. The convention is that we use the first item tuple for the sender and the second for the recipient. Only one channel is allowed between two participants in one direction, i.e. there cannot be 2 different channels identified by (A, B). A channel with the same para id in sender and recipient is invalid. That is, however, not enforced.
• Location
  A relative path between state-bearing consensus systems.
• ParaId
  Unique identifier of a parachain.
• Weight
• WeightMeter
  Meters consumed weight and a hard limit for the maximal consumable weight.

Enums

• AggregateMessageOrigin
  Aggregate message origin for the MessageQueue pallet.
• 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.
• 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.
• UmpQueueId
  Identifies a UMP queue inside the MessageQueue pallet.
• VersionedXcm
  A single XCM message, together with its version code.
• XcmBridgeHubCall
  A minimized version of pallet_xcm_bridge_hub::Call that can be used without a runtime.
• 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.

Traits

• BridgeMessageHandler
• Chain
• Decode
  Trait that allows zero-copy read of value-references from slices in LE format.
• DmpMessageHandler
  Something that should be called when a downward message is received.
• Encode
  Trait that allows zero-copy write of value-references to slices in LE format.
• Inspect
  Trait for providing balance-inspection access to a set of named fungible assets.
• Network
• Parachain
• RelayChain
• TestExt
• XcmpMessageHandler
  Something that should be called for each batch of messages received over XCMP.

Functions

• weight_within_threshold

Type Aliases

• AccountId
  Some way of identifying an account on the chain. We intentionally make it equivalent to the public key of our transaction signing scheme.
• Balance
  Balance of an account.
• BridgeLaneId
• InteriorLocation
  A relative location which is constrained to be an interior location of the context.
• XcmVersion
  A version of XCM.

Derive Macros

• Decode
  Derive parity_scale_codec::Decode and for struct and enum.
• Encode
  Derive parity_scale_codec::Encode and parity_scale_codec::EncodeLike for struct and enum.
