Function encode_buf 

pub fn encode_buf<'a, T, W>(input: &T, buf: &mut String, wrap: W)
where
    T: ?Sized + AsRef<[u8]>,
    W: Into<WrapOptions<'a>>,

Encode arbitrary octets as base65536. Writes into the supplied output buffer, growing it if needed.

The wrap option allows wrapping the output every so many characters, optionally with a supplied string using WrapOptions.

Unless called with ignore_garbage, decode and decode_buf will fail on output generated with a wrap. This is to match behaviour with the original implementation.

Panics

Panics if set to wrap every 0 columns.

Examples

Without word wrapping:

use base65536::encode_buf;

let mut buf = String::new();
encode_buf("hello world", &mut buf, None);

assert_eq!("驨ꍬ啯𒁷ꍲᕤ", buf);

With word wrapping:

use base65536::encode_buf;

let mut buf = String::new();
base65536::encode_buf(
    "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed \
     do eiusmod tempor incididunt ut labore et dolore magna \
     aliqua. Ut enim ad minim veniam, quis nostrud exercitation \
     ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis \
     aute irure dolor in reprehenderit in voluptate velit esse \
     cillum dolore eu fugiat nulla pariatur. Excepteur sint \
     occaecat cupidatat non proident, sunt in culpa qui officia \
     deserunt mollit anim id est laborum.", &mut buf, 80);

assert_eq!(buf.lines().next()?.chars().count(), 80);

With word wrapping using a custom line ending:

use base65536::{WrapOptions, encode_buf};

let mut buf = String::new();
base65536::encode_buf(
    "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed \
     do eiusmod tempor incididunt ut labore et dolore magna \
     aliqua. Ut enim ad minim veniam, quis nostrud exercitation \
     ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis \
     aute irure dolor in reprehenderit in voluptate velit esse \
     cillum dolore eu fugiat nulla pariatur. Excepteur sint \
     occaecat cupidatat non proident, sunt in culpa qui officia \
     deserunt mollit anim id est laborum.",
    &mut buf,
    WrapOptions::WrapAtWith(80, "\r\n"));

assert_eq!(buf.lines().next()?.chars().count(), 80);
