Trait rustc_serialize::base64::FromBase64

pub trait FromBase64 {
    fn from_base64(&self) -> Result<Vec<u8>, FromBase64Error>;
}

A trait for converting from base64 encoded values.

Required Methods

fn from_base64(&self) -> Result<Vec<u8>, FromBase64Error>

Converts the value of self, interpreted as base64 encoded data, into an owned vector of bytes, returning the vector.

Implementations on Foreign Types

impl FromBase64 for str

fn from_base64(&self) -> Result<Vec<u8>, FromBase64Error>

Convert any base64 encoded string (literal, @, &, or ~) to the byte values it encodes.

You can use the String::from_utf8 function to turn a Vec<u8> into a string with characters corresponding to those values.

Example

This converts a string literal to base64 and back.

extern crate rustc_serialize;
use rustc_serialize::base64::{ToBase64, FromBase64, STANDARD};

fn main () {
    let hello_str = b"Hello, World".to_base64(STANDARD);
    println!("base64 output: {}", hello_str);
    let res = hello_str.from_base64();
    if res.is_ok() {
      let opt_bytes = String::from_utf8(res.unwrap());
      if opt_bytes.is_ok() {
        println!("decoded from base64: {:?}", opt_bytes.unwrap());
      }
    }
}
