Enum Request 

pub enum Request {
    Read(Vec<u8>),
    Write(Vec<u8>),
    WriteSession {
        client_id: Uuid,
        seq: u64,
        command: Vec<u8>,
    },
    Status,
    ChangeMembership {
        voters: HashSet<NodeID>,
    },
}

客户端请求，通常透传给状态机。

Variants

Read(Vec<u8>)

状态机读命令，经 State::read 执行。不复制，仅在领导者上求值。

Write(Vec<u8>)

状态机写命令，经 State::apply 执行。复制到所有节点，结果必须确定。

WriteSession

带客户端 session 的写：日志中保存 (client_id, seq)，apply 时去重。

Fields

client_id: Uuid

seq: u64

command: Vec<u8>

Status

向领导者查询 Raft 集群状态。

ChangeMembership

变更集群投票成员为目标集合（联合共识）。

Fields

voters: HashSet<NodeID>
