Crate blocks_iterator

Blocks Iterator

Read bitcoin blocks directory containing blocks*.dat files, and produce a ordered stream of BlockExtra

Re-exports

pub use bitcoin;

pub use fxhash;

pub use glob;

pub use log;

pub use structopt;

Structs

BlockExtra

The bitcoin block and additional metadata returned by the iterate method

Config

Configuration parameters, most important the bitcoin blocks directory

FsBlock

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.

Functions

iterate

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.

periodic_log_level

Utility method usually returning log::Level::Debug but when i is divisible by 10_000 returns log::Level::Info
