Theawesome-cppis included, what is the best thing about this protruding libhv library?

libhvis similar to

Thelibevent、libev、libuvcross -platform library provides simpler interfaces and richer protocols.

libhv source code directoryecho-serversdisplayedasio、libevent、libev、libhv、libuv、muduo、poco7 samples of Echo-Server in the network library.

// Libhv Echo-Server Example 
 #include "hloop.h" 

 void on_close (hio_t* IO) { 
 } 

 void on_recv (HIO_T* IO, VOID* buf, int Readbytes) { 
     hio_write (IO, Buf, Readbytes); 
 } 

 void on_accept (hio_t* IO) { 
     hio_setcb_close (IO, ON_Close); 
     hio_setcb_read (IO, ON_RECV); 
     hio_read (IO); 
 } 

 int Main (int argc, char ** argv) { 
     if (ARGC <2) {{ 
         Printf ("usage: cmd port \ n"); 
         Return -10; 
     } 
     int Port = ATOI (ARGV [1]); 

     hlop_t* love = hloop_new (0); 
     hio_t* listnio = hloop_create_tcp_server (loop, "0.0.0.0", port, on_accept); 
     if (listnio == null) { 
         Return -20; 
     } 
     hloop_run (loop); 
     hlop_free (& loop); 
     Return 0; 
 }

pressure test results map:

It can be found that the performance of each library is comparable, but the libhv interface is the easiest and easy to use.
Specifically reflected:

• Provide a monitoring port to create TCP services. You do n’t need to write the bottom code of the socket (libev, libuv, you need to call the process by processsocket->bind->listen->accept）；
• hread_cb，hio_writeprototype and system callread、writeSimilar, no memory and cognitive burden;
• IO read and write abnormalities, disconnects, etc.

  Treatment inhclose_cb;

• No need to force the application layer buffer, the LibhV incident cycle provides a default ReadBuf (one loop per thread，one readbuf per loop), of course you can also callhio_set_readbufProvide your own buffer to avoid subsequentmemcpy；

libhv borrowed from Nginxmaster-workersMulti -process model, concurrent number, throughput, and even faintly exceed Nginx

// http API Server Example 
 #include "httpserver.h" 

 int main () {) 
     Httpservice service; 
     service.base_url = "/v1/api"; 
     Service.post ("/Echo", [] (httprequest* reQ, httpresponse* res) { 
         res-> body = req-> body; 
         Return 200; 
     }); 

     http_server_t server; 
     Server.Port = 8080; 
     server.service = & service; 
     http_server_run (& Server); 
     Return 0; 
 }
