Feature flags

By default openraft enables no features.

• bt: attaches backtrace to generated errors.

• serde: derives serde::Serialize, serde::Deserialize for type that are used in storage and network, such as Vote or AppendEntriesRequest.

• single-term-leader: allows only one leader to be elected in each term. This is the standard raft policy, which increases election confliction rate but reduce LogId((term, node_id, index) to (term, index)) size. Read more about how it is implemented in vote

• compat-07: provides additional data types to build v0.7 compatible RaftStorage.

  compat-07 = ["compat", "single-term-leader", "serde", "dep:or07", "compat-07-testing"]
  compat-07-testing = ["dep:tempdir", "anyhow", "dep:serde_json"]
