Instance Method

readBlock(at:)

Reads a previously-processed block from disk by its block tree entry.

func readBlock(at entry: BlockTreeEntry) -> Block?

Parameters

entry: The block tree entry pointing to the block.

Return Value

The block, or nil on read failure.

Discussion

Returns nil when the block index lists the entry but the block body is not on disk — e.g., an in-memory chainstate, a pruned data directory, or an entry from a side chain that was never fully validated.
