Data is often persisted and transmitted in binary format rather than strings, hence the interoperability between strings and byte slices help perform these conversions efficiently. However, care must be taken using these functions since the entire string is deep copied and repeated use may increase th...

Considering Golang is widely as a backend language, and those kind of calling has been put on the hot path. Solution: Simply add a string factory to package strings, exported one function New([]byte) string which converts bytes to string with the memory allocation optimised, and a ...

Golang Error Convert To String 学习golang 的过程中,会在很多情况下接触 error,实际上是 interface 类型,下面是它的定义: Go 语言的接口设计是非侵入式的,只要实现对应 interface 的方法就可以,所以只要实现 Error() 方法的类型都属于 error 接口类型。 创建 error 最简单的方法就是调用 errors.New 函数,...
