@polkadot/types
Implementation of the types and their (de-)serialisation via parity-codec.
Primitive types
There primitive types are available: Bool, Bytes, Data, H160, H256, H512, I8, I16, I32, I64, I128, I256, Method, Moment, Null, StorageData, StorageKey, Text, Type, U8, U16, U32, U64, U128, U256, USize
Substrate types
These types implement specific types that are found as part of the Substrate base: AccountId, AccountIndex, Address, Amount, AssetOf, AttestedCandidate, AuthorityId, Balance, BalanceOf, Block, BlockNumber, CodeHash, Digest, Event, EventRecord, Extrinsic, ExtrinsicEra, ExtrinsicSignature, Gas, Hash, Header, InherentOfflineReport, Justification, KeyValue, MisbehaviorReport, NewAccountOutcome, Nonce, Origin, ParaId, Perbill, Permill, PrefabWasmModule, PropIndex, Proposal, ProposalIndex, ReferendumIndex, ReferendumInfo, Schedule, SeedOf, SessionKey, Signature, SignaturePayload, StoredPendingChange, ValidatorPrefs, VestingSchedule, Vote, VoteIndex, VoteThreshold
Codec types
These are the base types of the codec, typically not used directly, but rather inherited from to create specific types: Base, Compact, Enum, EnumType, Option, Set, Struct, Tuple, U8a, U8aFixed, UInt, Vector
RPC types
These types are not used in the runtime, but rather are used in RPC results: ChainProperties, ExtrinsicStatus, Health, Json, NetworkState, Metadata, PeerInfo, PendingExtrinsics, RuntimeVersion, SignedBlock, StorageChangeSet
Derived types
Some types are extended from the base to provide additional information: HeaderExtended, ReferendumInfoExtended
