Function base16::encode_config_buf

pub fn encode_config_buf<T: ?Sized + AsRef<[u8]>>(
    input: &T, 
    cfg: EncConfig, 
    dst: &mut String
) -> usize

Encode input into the end of the provided buffer. Returns the number of bytes that were written.

Only allocates when dst.size() + (input.len() * 2) >= dst.capacity().

Example

let messages = &["Taako, ", "Merle, ", "Magnus"];
let mut buffer = String::new();
for msg in messages {
    let bytes_written = base16::encode_config_buf(msg.as_bytes(),
                                                  base16::EncodeUpper,
                                                  &mut buffer);
    assert_eq!(bytes_written, msg.len() * 2);
}
assert_eq!(buffer, "5461616B6F2C204D65726C652C204D61676E7573");

Availability

This function is only available when the alloc feature is enabled, as it needs write to a String.
