Golang advanced fine-tuning technology

This article shares some tips that can help us write more simplified and efficient Golang code, thus obtaining a better development experience. Original text: Fine-Tuning Golang: Advanced Techniques for Code Optimization [1]

This article is a comprehensive guide to Golang code optimization techniques, helping us unleash the full potential of Golang applications, improve performance, simplify development, and achieve a more efficient and powerful coding experience.

During the project development process, I found that there was often duplicate code, and sometimes certain technologies were ignored, which was not discovered until the work was reviewed.

In order to solve this problem, I developed a solution. This is very helpful for myself and I believe it will also be useful for others.

Here are some useful and versatile code snippets randomly selected from my utility library, without specific categories or tricks for specific systems.

Techniques for tracking execution time

If you want to track the execution time of a function in Go, there is a simple and efficient technique that only requires one line of code and the defer keyword. All you need is a TrackTimefunction:

// Utility
func TrackTime(pre time.Time) time.Duration {
  elapsed := time.Since(pre)
  fmt.Println("elapsed:", elapsed)  return elapsed
}func TestTrackTime(t *testing.T) {
  defer TrackTime(time.Now()) // <…
