Module 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.

Structs

ChainSync

The main data structure which contains all the state for a chains active syncing strategy.

GapSyncBodyPolicy

Which block bodies gap sync downloads while backfilling the block history below a warp-synced block.

Functions

validate_blocks

Validate that the given blocks are correct. Returns the number of the first block in the sequence.

Type Aliases

GapSyncBodyPolicyProvider

Resolves the GapSyncBodyPolicy lazily, when a ChainSync instance is created.
