Function bs62::encode_num

pub fn encode_num<T: ToBigUint>(num: &T) -> String

Convert a base10 (decimal) number to base62.

Algorithm

The input number is divided (with reminder) by 62 (the base). The remainder is then used as an index to get a char from the alphabet [0-9][A-Z][a-z] and the char is stored an a list. The floored quotiont is then used as the new number and is again divided (with remainder) by 62 and so on. At the end, when the number becomes zero, and the las remainer was used to get char from the alphabet, the list of chars is reversed and converted to a string.

Panics

Panics if the num can not be converted to BigUint (e.g. if num is negative).

Example

let num = 1337;
let encoded = bs62::encode_num(&num);

assert_eq!(encoded, "LZ")
