Struct lair_keystore::dependencies::base64::read::DecoderReader
[−]pub struct DecoderReader<'a, R> where
R: 'a + Read, { /* private fields */ }
Expand description
A Read
implementation that decodes base64 data read from an underlying reader.
Examples
use std::io::Read;
use std::io::Cursor;
// use a cursor as the simplest possible `Read` -- in real code this is probably a file, etc.
let mut wrapped_reader = Cursor::new(b"YXNkZg==");
let mut decoder = base64::read::DecoderReader::new(
&mut wrapped_reader, base64::STANDARD);
// handle errors as you normally would
let mut result = Vec::new();
decoder.read_to_end(&mut result).unwrap();
assert_eq!(b"asdf", &result[..]);

fn read(&mut self, buf: &mut [u8]) -> Result<usize, Error>
fn read(&mut self, buf: &mut [u8]) -> Result<usize, Error>
Decode input from the wrapped reader.
Under non-error circumstances, this returns Ok
with the value being the number of bytes
written in buf
.
Where possible, this function buffers base64 to minimize the number of read() calls to the delegate reader.
Errors
Any errors emitted by the delegate reader are returned. Decoding errors due to invalid
base64 are also possible, and will have io::ErrorKind::InvalidData
.
