Detailed Description

单个服务端连接的有界异步发送状态。

Note

由 TcpServer 创建和管理；公开定义是为了让 handler 安全持有共享状态，业务代码不应直接修改字段。

Member Data Documentation

close_after_flush

bool stt::network::ConnectionWriteState::close_after_flush =false

是否等待队列排空后关闭。

close_requested

bool stt::network::ConnectionWriteState::close_requested =false

是否请求 Reactor 关闭连接。

closed

bool stt::network::ConnectionWriteState::closed =false

状态是否已停止接受数据。

connection_obj_fd

uint64_t stt::network::ConnectionWriteState::connection_obj_fd =0

fd 复用保护代次。

fd

int stt::network::ConnectionWriteState::fd =-1

底层文件描述符。

front_offset

size_t stt::network::ConnectionWriteState::front_offset =0

队首数据块已写出的偏移。

max_queued_bytes

size_t stt::network::ConnectionWriteState::max_queued_bytes =4UL*1024UL*1024UL

本连接待发高水位。

mutex

std::mutex stt::network::ConnectionWriteState::mutex

保护本结构中其余可变字段。
