Module grin_chain::types

Base types that the block chain pipeline requires.

Structs

• CommitPos
  Minimal struct representing a known MMR position and associated block height.
• NoStatus
  Do-nothing implementation of TxHashsetWriteStatus
• NoopAdapter
  Dummy adapter used as a placeholder for real implementations
• Options
  Options for block validation
• OutputRoots
  A helper for the various output roots.
• PIBDSegmentContainer
  Container for entry in requested PIBD segments
• SyncState
  Current sync state. Encapsulates the current SyncStatus.
• Tip
  The tip of a fork. A handle to the fork ancestry from its leaf in the blockchain tree. References the max height and the latest and previous blocks for convenience and the total difficulty.
• TxHashSetRoots
  A helper for the various txhashset MMR roots.
• TxHashsetDownloadStats
  Stats for TxHashsetDownload stage

Enums

• BlockStatus
  Status of an accepted block.
• SyncStatus
  Various status sync can be in, whether it’s fast sync or archival.

Traits

• ChainAdapter
  Bridge between the chain pipeline and the rest of the system. Handles downstream processing of valid blocks by the rest of the system, most importantly the broadcasting of blocks to our peers.
• TxHashsetWriteStatus
  Inform the caller of the current status of a txhashset write operation, as it can take quite a while to process. Each function is called in the order defined below and can be used to provide some feedback to the caller. Functions taking arguments can be called repeatedly to update those values as the processing progresses.
