Detailed introduction to Golang parameter annotations

Golang is a very popular programming language, and one of its biggest features is its powerful type system. In Golang, parameter annotations are a very important tool that can help programmers better understand the role of a function or method. In this article, we will introduce the relevant knowledge of Golang parameter annotation.

Parameter comments in Golang have two forms: // and /* */. The two forms of parameter annotations are introduced below.

1. // Parameter comments in the form

This form of parameter comments is written directly after the parameter definition of the function or method. Comments Contents are separated by commas and spaces. For example:

func foo(a int, b string) {
    // a: 参数a，表示...
    // b: 参数b，表示...
    // ...
}

where a: parameter a, means... and b: parameter b, means... is the parameter comment. This form of comment can be used for single-line comments or multi-line comments. Using this form of annotation, the meaning of each parameter can be written directly in the annotation, making it easier for other developers to view and understand the code.

2. /* */ Parameter comments in the form

This form of parameter comments is written before the definition of the function or method, using Used to describe the meaning and role of the entire function or method. The comment content starts with the @ symbol, followed by the parameter name and parameter value. For example:

// Foo函数的作用是...
// @param a int 参数a，表示...
// @param b string 参数b，表示...
func Foo(a int, b string) {
    // ...
}

@param here represents the parameter, followed by the parameter name and parameter value. This form of annotation is typically used for documentation generation of functions or methods. When reading code, developers can obtain basic information and parameter meanings of functions or methods by viewing such comments.

Summary

Parameter annotations in Golang are a very important and useful tool that can help developers better understand the code. By using parameter annotations, you can make the code more readable and understandable, and improve the maintainability of the code. When writing Golang code, be sure to pay attention to the use of parameter annotations.
