Struct Client 

pub struct Client { /* private fields */ }

可向任意本地节点提交请求的客户端（跟随者会转发到领导者）。

Implementations

impl Client

pub fn register_node( &self, id: NodeID, tx: Sender<(Request, Sender<Result<Response>>)>, )

注册或更新某节点的请求通道（节点 start 后调用）。

pub fn unregister_node(&self, id: NodeID)

pub fn preferred_hint(&mut self, id: NodeID)

提示下次优先向该节点发请求。

pub fn request(&mut self, request: Request) -> Result<Response>

pub fn request_on( &mut self, node_id: NodeID, request: Request, ) -> Result<Response>

只向指定节点发请求（仍在 Abort 时对该节点重试）。

pub fn put(&mut self, key: &str, value: &str) -> Result<Index>

pub fn put_on( &mut self, node_id: NodeID, key: &str, value: &str, ) -> Result<Index>

pub fn get(&mut self, key: &str) -> Result<Option<String>>

pub fn scan(&mut self) -> Result<BTreeMap<String, String>>

pub fn status(&mut self) -> Result<Status>

pub fn status_on(&mut self, node_id: NodeID) -> Result<Status>

pub fn change_membership(&mut self, voters: HashSet<NodeID>) -> Result<Index>

变更集群成员（目标投票人集合）。需协议侧支持 Request::ChangeMembership。

Trait Implementations

impl Clone for Client

fn clone(&self) -> Client

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
