Function decode_into

pub fn decode_into<B>(bytes: B, output: &mut [u8]) -> Result<usize, Error>
where
    B: AsRef<[u8]>,

Decodes Crockford Base32-encoded bytes into a provided output buffer.

Returns

• Ok(usize): The number of bytes written to the output buffer.
• Err(Error): If any errors occur during the decoding process.

Errors

• Error::InvalidString if the input contains non-ASCII characters.
• Error::InvalidChar if the character is not found in C32_ALPHABET.
• Error::InvalidBufferSize if the output buffer is too small.
• Error::TryFromInt when bit arithmetic operations exceeds bounds.

Examples

let bytes = b"1TQ6WBNCMG62S10CSMPWSBD";

// allocate a buffer with enough capacity
let mut buffer = [0; 32];

// decode bytes into the buffer
let written = c32::decode_into(bytes, &mut buffer)?;

let expected = b"usque ad finem";
assert_eq!(&buffer[..written], expected);
