source · [−]Expand description
Blocks Iterator
Read bitcoin blocks directory containing blocks*.dat files, and produce a ordered stream
of BlockExtra
Re-exports
Structs
The bitcoin block and additional metadata returned by the [iterate] method
Configuration parameters, most important the bitcoin blocks directory
Before reorder we keep only the position of the block in the file system and data relative
to the block hash, the previous hash and the following hash (populated during reorder phase)
We will need to read the block from disk again, but by doing so we will avoid using too much
memory in the [OutOfOrderBlocks] map.
Contains counter and instants to provide per period stats over transaction and blocks processed
Utility used to return true after period
Iterator to use un Unix-style pipe composition when receiving BlockExtra from stdin and propogating those to stdout
Functions
Return an Iterator of BlockExtra read from blocks*.dat contained in the config.blocks_dir
Blocks returned are iterated in order, starting from the genesis to the highest block
(minus config.max_reorg) in the directory, unless config.stop_at_height is specified.
Read blocks*.dat contained in the config.blocks_dir directory and returns BlockExtra
through a channel supplied from the caller. Blocks returned are ordered from the genesis to the
highest block in the directory (minus config.max_reorg).
In this call threads are spawned, caller must call std::thread::JoinHandle::join on the returning handle.
Utility method usually returning log::Level::Debug but when i is divisible by every returns log::Level::Info
