Crate bp_runtime

Primitives that may be used at (bridges) runtime level.

Re-exports

• pub use sp_runtime::paste;

Modules

• extensions
  Primitives that may be used for creating signed extensions for indirect runtimes.
• messages
  Primitives that may be used by different message delivery and dispatch mechanisms.

Macros

• decl_bridge_finality_runtime_apis
  Convenience macro that declares bridge finality runtime apis and related constants for a chain. This includes:
• decl_bridge_messages_runtime_apis
  Convenience macro that declares bridge messages runtime apis and related constants for a chain. This includes:
• decl_bridge_runtime_apis
  Convenience macro that declares bridge finality runtime apis, bridge messages runtime apis and related constants for a chain. The name of the chain has to be specified in snake case (e.g. bridge_hub_polkadot).
• generate_static_str_provider
  A macro that generates StaticStrProvider with the string set to its stringified argument.

Structs

• BoundedStorageValue
  A bounded runtime storage value.
• HeaderId
  Generic header Id.
• ParachainIdOf
  Adapter for Get<u32> to access PARACHAIN_ID from trait Parachain
• PreComputedSize
  Pre-computed size.
• StorageProofChecker
  This struct is used to read storage values from a subset of a Merklized database. The “proof” is a subset of the nodes in the Merkle structure of the database, so that it provides authentication against a known Merkle root as well as the values in the database themselves.
• UnverifiedStorageProofParams
  Storage values size requirements.

Enums

• BasicOperatingMode
  Basic operating modes for a bridges module (Normal/Halted).
• EncodedOrDecodedCall
  Chain call, that is either SCALE-encoded, or decoded.
• OwnedBridgeModuleError
  Error generated by the OwnedBridgeModule trait.
• StorageProofError
  Errors that can occur when interacting with UnverifiedStorageProof and VerifiedStorageProof.
• TransactionEra
  Era of specific transaction.

Constants

• NO_INSTANCE_ID
  Use this when something must be shared among all instances.

Traits

• Chain
  Minimal Substrate-based chain representation that may be used from no_std environment.
• HeaderIdProvider
  Generic header id provider.
• OperatingMode
  Operating mode for a bridge module.
• OwnedBridgeModule
  Bridge module that has owner and operating mode
• Parachain
  Minimal parachain representation that may be used from no_std environment.
• RangeInclusiveExt
  A trait defining helper methods for RangeInclusive (start..=end)
• Size
  Anything that has size.
• StaticStrProvider
  Trait that provides a static str.
• StorageDoubleMapKeyProvider
  Can be used to access the runtime storage key of a StorageDoubleMap.
• StorageMapKeyProvider
  Can be use to access the runtime storage key of a StorageMap.
• UnderlyingChainProvider
  A trait that provides the type of the underlying chain.
• WeightExtraOps
  All extra operations with weights that we need in bridges.

Functions

• craft_valid_storage_proof
  Return valid storage proof and state root.
• grow_storage_proof
  Insert values in the provided trie at common-prefix keys in order to inflate the resulting storage proof.
• grow_storage_value
  Add extra data to the storage value so that it’ll be of given size.
• raw_storage_proof_size
  Calculates size for RawStorageProof.
• record_all_trie_keys
  Record all keys for a given root.
• storage_map_final_key
  This is a copy of the frame_support::storage::generator::StorageMap::storage_map_final_key for maps based on selected hasher.
• storage_value_final_key
  Returns the storage prefix for a specific pallet name and storage name.
• storage_value_key
  This is how a storage key of storage value is computed.
