b64

Go library convert Int64 or Uint64 variable to string(11 symbols), and convert 11 symbols string back to int64 or uint64

What is it?

Library converts a single intenger to a string of 1 to 11 characters. Conversion is to reduce number characters when writing a long string of numbers.

Example: 1048575 (7 symbols) -> "D___" (4 symbols)

Yes, it is a regular base64 for use in a URL, but it works faster than the standard library "encoding/base64" And it made a little more comfortable when using a conversion of only one number

How to use?

######Convert from number to string package main

import "gopkg.in/webnice/b64.v1"

func main() {
    o := b64.NewUint64(10485251)
    print(o.String(), "\n")
	print(o.Uint64(), "\n")
}

Result:

n_4D
10485251

######Convert from string to number

package main

import "gopkg.in/webnice/b64.v1"

func main() {
	obj := b64.NewString("P____A____1")
	if obj.Error() != nil {
		panic(obj.Error())
	}
	print(obj.Uint64(), "\n")
	print(obj.Int64(), "\n")
}

Result:
