Struct Connection 

Source 
pub struct Connection { /* private fields */ }
Expand description

底层 TCP 连接封装

基于 tokio TcpStream + FutuCodec 的 Framed 连接， 提供异步发送/接收 FutuFrame 的能力。

Implementations§

Source§

impl Connection

Source

pub async fn connect(addr: &str) -> Result<Self, FutuError>

建立 TCP 连接

Source

pub async fn send(&mut self, frame: FutuFrame) -> Result<(), FutuError>

发送一个协议帧

Source

pub async fn recv(&mut self) -> Result<Option<FutuFrame>, FutuError>

接收下一个协议帧

返回 None 表示连接已关闭。

Source

pub fn build_frame(proto_id: u32, serial_no: u32, body: Vec<u8>) -> FutuFrame

发送原始 protobuf 数据，自动构建 FutuFrame
