Crate raft_consensus

Raft

This is a crate containing a Raft consensus protocol implementation and encoding/decoding helpers. This is a logic-only crate without any network implementations.

To use this crate in implementation, one should do the following:

• determine and implement(or take ready ones) state machine and persistent log implementations

• pass all raft-related messages from receivers/transmitters to Consensus structure

• define a CollectionHandle that which functions are called at different stages of consensus defining actions depending on receive/transmit environment

Re-exports

pub use consensus::Consensus;

pub use consensus::ConsensusHandler;

pub use shared::SharedConsensus;

pub use persistent_log::Log;

pub use state_machine::StateMachine;
