To loop through struct types in Go , makes use of the reflect package. The Reflect package implements run-time reflection, hence allowing a program to modify objects with arbitrary types.Examplego package main import ( "fmt" "reflect" ) type User struct { FirstName string Lastname string ...

一个M调度goroutine执行的过程是一个loop; 当M执行某一个goroutine时候如果发生了syscall或则其余阻塞操作,M会阻塞,如果当前有一些G在执行,runtime会把这个线程M从P中摘除(detach),然后再创建一个新的操作系统的线程(如果有空闲的线程可用就复用空闲线程)来服务于这个P; ...
