Trait rustc_serialize::base64::FromBase64
[−]
[src]
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>
[src]
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()); } } }
