This article will explain in detail the example analysis of channel channel in Go language. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

I. the background of 1.channel, the basic concept of Go language channel.

In order to ensure the correctness of data exchange, the mutex must be used to lock the memory. The model of go language concurrency is CSP, which advocates sharing memory through communication rather than sharing memory. The channel happens to meet this requirement.

The way 2.channel works

Channel is similar to a queue, which satisfies the first-in-first-out rule and strictly ensures the order of sending and receiving data. Each channel can only pass through fixed types of data. If the channel transmits large structures and strings, the corresponding pointer can be passed in to save space as much as possible.

Second, the use of channel syntax 1. Channel declaration and initialization / / define the use of a channel object, where int can be changed to its own desired type var a chan int / / initialize a channel with only one location (the first parameter represents the channel type, and the second parameter represents how many locations the channel has) / / the new data will not be stored (blocking) a = make (chan int,1) 2 after the location is full. Put the data into the channel
