Module polkadot_service::generic

Generic implementations of crate::traits::Header, crate::traits::Block and crate::traits::ExtrinsicLike.

Structs

• Block
  Abstraction over a substrate block.
• CheckedExtrinsic
  Definition of something that the external world might want to say; its existence implies that it has been checked and is good, particularly with regards to the signature.
• Digest
  Generic header digest.
• Header
  Abstraction over a block header for a substrate chain.
• SignedBlock
  Abstraction over a substrate block and justification.
• SignedPayload
  A payload that has been signed for an unchecked extrinsics.
• UncheckedExtrinsic
  An extrinsic right from the external world. This is unchecked and so can contain a signature.

Enums

• BlockId
  Something to identify a block.
• DigestItem
  Digest item that is able to encode/decode ‘system’ digest items and provide opaque access to other items.
• DigestItemRef
  A ‘referencing view’ for digest item. Does not own its contents. Used by final runtime implementations for encoding/decoding its log items.
• Era
  An era to describe the longevity of a transaction.
• ExtrinsicFormat
  The kind of extrinsic this is, including any fields required of that kind. This is basically the full extrinsic except the Call.
• OpaqueDigestItemId
  Type of a digest item that contains raw data; this also names the consensus engine ID where applicable. Used to identify one or more digest items of interest.
• Preamble
  A “header” for extrinsics leading up to the call itself. Determines the type of extrinsic and holds any necessary specialized data.

Constants

• EXTRINSIC_FORMAT_VERSION
  Current version of the UncheckedExtrinsic encoded format.

Type Aliases

• ExtensionVersion
  Type to represent the version of the Extension used in this extrinsic.
• Phase
  Era phase
• UncheckedSignaturePayload
  The SignaturePayload of UncheckedExtrinsic.
