type BlockRequest 

type BlockRequest struct {

type BlockStore 

type BlockStore struct {
	// contains filtered or unexported fields
}

BlockStore is a simple low level store for blocks.

There are three types of information stored:

  • BlockMeta: Meta information about each block
  • Block part: Parts of each block, aggregated w/ PartSet
  • Commit: The commit part of each block, for gossiping precommit votes

Currently the precommit signatures are duplicated in the Block parts as well as the Commit. In the future this may change, perhaps by moving the Commit data outside the Block. (TODO)

// NOTE: BlockStore methods will panic if they encounter errors // deserializing loaded data, indicating probable corruption on disk.
