Module sc_network_sync::strategy::chain_sync

Contains the state of the chain synchronization process

At any given point in time, a running node tries as much as possible to be at the head of the chain. This module handles the logic of which blocks to request from remotes, and processing responses. It yields blocks to check and potentially move to the database.

Usage

The ChainSync struct maintains the state of the block requests. Whenever something happens on the network, or whenever a block has been successfully verified, call the appropriate method in order to update it.
