WebGo has a way of making these accidental similarities explicit through a type known as an Interface. Here is an example of a Shape interface: type Shape interface { area () float64 } Like a struct an interface is created using the type keyword, followed by a name and the keyword interface. But instead of defining fields, we define a “method set”. Web参考资料 golang interface解读 Go编程模式：切片，接口，时间和性能 酷 壳 - CoolShell 理解interface golang语言defer特性详解.md - 简书 (jianshu.com) 手摸手Go 并发编程基 … hawk catcher

Structs and Interfaces — An Introduction to Programming in Go

Web什么是 interface 在面向对象编程中，可以这么说：“接口定义了对象的行为”， 那么具体的实现行为就取决于对象了。 在 Go 中， 接口是一组方法签名。当一个类型为接口中的所有方法提供定义时，它被称为实现该接口… WebThe io package has this behaviour: type Writer interface { Write (p []byte) (n int, err error) } And this behaviour (interface) is used across many "child/derived" types (like buffers, network connection etc). So it would be awesome so see this kind of relationship visually, maybe generated from a tool or as documentation. WebThe Go programming language is an open source project to make programmers more productive. Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. boss orthopedic hilton head
