Module hotshot_types::utils

Utility functions, type aliases, helper structs and enum definitions.

Structs

• BuilderCommitment
  Commitment that builders use to sign block options. A thin wrapper around a Sha256 digest.
• RoundFinishedEvent
  A struct containing information about a finished round.
• View
  This exists so we can perform state transitions mutably

Enums

  For the wire format, we use bincode with the following options:
• epoch_from_block_number
  Returns an epoch number given a block number and an epoch height
• is_last_block_in_epoch
  Returns true if the given block number is the last in the epoch based on the given epoch height.
• mnemonic
  A function for generating a cute little user mnemonic from a hash

Type Aliases

• LeafCommitment
  The hash of a leaf.
• Sha256Digest 🔒
  Type alias for byte array of SHA256 digest length
• StateAndDelta
  Optional validated state and state delta.
