go extend

go-extend

go-extend collects some commonly used operation functions to help complete development work faster and reduce duplicate code.

It collects various miscellaneous functions and categorizes them to make it easier for users to find them. It can greatly improve development efficiency and program running performance. It provides effective methods with the greatest premise of ensuring performance. Make some modifications to some functions or libraries in the standard library to greatly improve their performance, but it is not used to replace the standard library functions. These functions are often effective in some scenarios, but some functions can be used to replace the standard library functions. , they maintain consistent functionality and are quite secure.

Some package or function usage examples and analysis can be found on my blog (https://blog.thinkeridea.com).

Install

$ go get  github.com/thinkeridea/go-extend/...

specification:

• Use the ex prefix consistent with the standard library package name to avoid conflicts with standard library packages.
• doc.go in the package directory serves as the package description document

Performance testing

Some functions in the package will undergo performance testing, including performance comparison of each revision. They are generally located in benchmark directory under the respective package. The performance test results can be quickly browsed in benchmark.md.

List of standard library function improvements

Used to replace the functions of the standard library. They have the same functions as the standard library functions and have better performance:

• exstrings.Join This method is a modification of the standard library strings.Join. It can effectively reduce memory allocation when combined with the unsafe package.
• exstrings.Repeat This method is a modification of the standard library strings.Repeat, which can effectively reduce memory allocation for creating large strings.
• exstrings.Replace replaces a string. This method is a modification of the standard library strings.Replace. Together with the unsafe package, it can effectively reduce memory allocation.

Use this function to improve the standard library. They have basically the same functionality as the standard library, but they all have better performance:

• exbytes.Replace uses in-place replacement to directly modify the input data for better performance.
• exstrings.JoinToBytes It responds to a []byte type, effectively avoiding type conversion
• exstrings.RepeatToBytes It responds to a []byte type, effectively avoiding type conversion
• exstrings.ReplaceToBytes It responds to a []byte type, effectively avoiding type conversion
• exstrings.UnsafeReplaceToBytes It responds to a []byte type and performs in-place replacement. It cannot receive a literal string, otherwise a serious error will occur.
