components::TcpAcceptorBase Class Reference

#include <userver/components/tcp_acceptor_base.hpp>

Detailed Description

Component for accepting incoming TCP connections.

Each accepted socket is processed in a new coroutine by ProcessSocket of the derived class.

Static options:

Name	Description	Default value
port	port to listen on	-
unix-socket	unix socket to listen on instead of listening on a port	''
task_processor	task processor to accept incoming connections	-
backlog	max count of new connections pending acceptance	1024
no_delay	whether to set the TCP_NODELAY option on incoming sockets	true
sockets_task_processor	task processor to process accepted sockets	value of task_processor
