Function quoted_printable::decode

pub fn decode<R: AsRef<[u8]>>(
    input: R, 
    mode: ParseMode
) -> Result<Vec<u8>, QuotedPrintableError>

Decodes a piece of quoted-printable data.

The quoted-printable transfer-encoding is defined in IETF RFC 2045, section 6.7. This function attempts to decode input that is conformant with that spec. Note that quoted-printable encoding is independent of charset, and so this function returns a Vec of bytes upon success. It is up to the caller to convert that to a String if desired; the charset required to do so must come from somewhere else.

Examples

    use quoted_printable::{decode, ParseMode};
    let decoded = decode("hello=3Dworld=0D=0A".as_bytes(), ParseMode::Robust).unwrap();
    assert_eq!("hello=world\r\n", String::from_utf8(decoded).unwrap());

Errors

If this function is called with ParseMode::Strict, then it may return a QuotedPrintableError if it detects that the input does not strictly conform to the quoted-printable spec. If this function is called with ParseMode::Robust, then it will attempt to gracefully handle any errors that arise. This might result in input bytes being stripped out and ignored in some cases. Refer to IETF RFC 2045, section 6.7 for details on what constitutes valid and invalid input, and what a "robust" implementation would do in the face of invalid input.
