Low-level types used throughout the Substrate code.

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.
• AccountIndex
  The type for looking up accounts. We don’t expect more than 4 billion of them.
• Balance
  Balance of an account.
• Block
  Block type.
• BlockId
  Block ID.
• BlockNumber
  An index to a block.
• DigestItem
  Digest item type.
• Hash
  A hash of some data used by the chain.
• Header
  Header type.
• Moment
  Type used for expressing timestamp.
• Nonce
  Index of a transaction in the chain.
• Signature
  Alias to 512-bit hash when used in the context of a transaction signature on the chain.
• Timestamp
  A timestamp: milliseconds since the unix epoch. u64 is enough to represent a duration of half a billion years, when the time scale is milliseconds.
