used by a parachain or PDK such as cumulus. AccountData All balance information for an account. Ancestor A unit struct which can be converted into a Location of the inner parents value. Assets A Vec of Assets. BlockWeightsLimits Block weight limits & base values configuration. BoundedSlice A bounded slice. BridgeMessage BridgeMessageDispatchError DefaultParaMessageProcessor DefaultRelayMessageProcessor Digest Generic header digest. HashMap A hash map implemented with quadratic probing and SIMD lookup. HeadData Parachain head data included in the chain. 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. LazyLock A value which is initialized on the first access. Location A relative path between state-bearing consensus systems. MessageQueuePallet The Pallet struct, the main type that implements traits and standalone
functions within the pallet. Mutex A mutual exclusion primitive useful for protecting shared data ParaId Unique identifier of a parachain. ParachainInherentData The inherent data that is passed by the collator to the parachain runtime. ParachainSystemPallet The Pallet struct, the main type that implements traits and standalone
functions within the pallet. Parent A unit struct which can be converted into a Location of parents value 1. 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. PhantomData Zero-sized type used to mark things that “act like” they own a T. RefCell A mutable memory location with dynamically checked borrow rules RelayStateSproofBuilder Builds a sproof (portmanteau of ‘spoof’ and ‘proof’) of the relay chain state. Storage Struct containing data needed for a storage. SystemPallet The Pallet struct, the main type that implements traits and standalone
functions within the pallet. Test Struct that helps with tests where either dispatchables or assertions need
to be reused. The struct keeps the test’s arguments of your choice in the generic Args.
These arguments can be easily reused and shared between the assertion functions
and dispatchable functions, which are also stored in Test.
Origin corresponds to the chain where the XCM interaction starts with an initial execution.
Destination corresponds to the last chain where an effect of the initial execution is expected
to happen. Hops refer to all the ordered intermediary chains an initial XCM execution can
provoke some effect on. TestAccount Struct that keeps account’s id and balance TestArgs Default Args provided by xcm-emulator to be stored in a Test instance TestContext Auxiliar struct to help creating a new Test instance VecDeque A double-ended queue implemented with a growable ring buffer. Weight WeightMeter Meters consumed weight and a hard limit for the maximal consumable weight. AggregateMessageOrigin Aggregate message origin for the MessageQueue pallet. CumulusAggregateMessageOrigin The origin of an inbound message. ExecuteOverweightError Errors that can happen when attempting to execute an overweight message with
ServiceQueues::execute_overweight() ParachainSystemCall Contains a variant per dispatchable extrinsic that this pallet has. ProcessMessageError Errors that can happen when attempting to process a message with
ProcessMessage::process_message() TimestampCall Contains a variant per dispatchable extrinsic that this pallet has. UmpQueueId Identifies a UMP queue inside the MessageQueue pallet. WeightLimit An optional weight limit. BRIDGED_MESSAGES Bridged messages, each message is: BridgeMessage DMP_DONE Downward messages that already processed by parachains, each message is: (to_para_id, relay_block_number, Vec<u8>) DOWNWARD_MESSAGES Downward messages, each message is: (to_para_id, [(relay_block_number, msg)]) HORIZONTAL_MESSAGES Horizontal messages, each message is: (to_para_id, [(from_para_id, relay_block_number, msg)]) INITIALIZED Flag indicating if global variables have been initialized for a certain Network LAST_HEAD Most recent HeadData of each parachain, encoded. PARA_IDS Parachains Ids a the Network UPWARD_MESSAGES Upward messages, each message is: (from_para_id, msg) Bounded Numbers which have upper and lower bounds Bridge BridgeMessageHandler Chain CheckAssertion Convert Infallible conversion trait. Generic over both source and destination types. ConvertLocation Means of converting a location into an account identifier. Debug ? formatting.Decode Trait that allows zero-copy read of value-references from slices in LE format. Deref Used for immutable dereferencing operations, like *v. Dispatchable A lazy call (module function and argument values) that can be executed via its dispatch
method. 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. EncodeLike A marker trait that tells the compiler that a type encode to the same representation as another
type. EnqueueMessage Can enqueue messages for multiple origins. Error Error is a trait representing the basic expectations for error values,
i.e., values of type E in Result<T, E>Get A trait for querying a single value from a type. HeaderT Something which fulfills the abstract idea of a Substrate header. It has types for a Number,
a Hash and a Hashing. It provides access to an extrinsics_root, state_root and
parent_hash, as well as a digest and a block number. Hooks The pallet hooks trait. This is merely an umbrella trait for: MaxEncodedLen Items implementing MaxEncodedLen have a statically known maximum encoded size. MessageQueueConfig Configuration trait of this pallet. Network OnFinalize See Hooks::on_finalize OnIdle See Hooks::on_idle OnInitialize See Hooks::on_initialize OriginTrait Methods available on frame_system::Config::RuntimeOrigin. Pair Trait suitable for typical cryptographic PKI key pair type. Parachain ProcessMessage Can process messages from a specific origin. RelayChain ServiceQueues Can service queues and execute overweight messages. SystemConfig Configuration trait of this pallet. TestExt XcmpMessageHandler Something that should be called for each batch of messages received over XCMP. Zero Defines an additive identity element for Self. blake2_256 Do a Blake2 256-bit hash and return result. get_public_from_string_or_panic Interprets the string s in order to generate a public key without password. type_name Returns the name of a type as a string slice. AccountId Some way of identifying an account on the chain. We intentionally make it equivalent
to the public key of our transaction signing scheme. AccountIdOf Balance Balance of an account. BlockNumberFor Type alias for the BlockNumber associated type of system config. BridgeLaneId DispatchResult This is the legacy return type of Dispatchable. It is still exposed for compatibility reasons.
The new return type is DispatchResultWithInfo. FRAME runtimes should use
frame_support::dispatch::DispatchResult. RelayBlockNumber The block number type used by Polkadot.
32-bits will allow for 136 years of blocks assuming 1 block per second. RelayChainBlockNumber The block number type used by Polkadot.
32-bits will allow for 136 years of blocks assuming 1 block per second. TestExternalities Type alias for Externalities implementation used in tests. XcmHash A hash type for identifying messages. Debug Derive macro generating an impl of the trait Debug. Decode Derive parity_scale_codec::Decode for struct and enum. Encode Derive parity_scale_codec::Encode and parity_scale_codec::EncodeLike for struct and enum. MaxEncodedLen Derive parity_scale_codec::MaxEncodedLen for struct and enum.
