pub const BASE64_MIME: Encoding;

MIME base64 encoding

This encoding is a static version of:

let mut spec = Specification::new();
spec.symbols.push_str("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/");
spec.padding = Some('=');
spec.wrap.width = 76;
spec.wrap.separator.push_str("\r\n");
assert_eq!(BASE64_MIME, spec.encoding().unwrap());

It does not exactly conform to RFC2045 because it does not print the header and does not ignore all characters.
