Function decode_check

pub fn decode_check<'a, S>(str: S) -> Result<(u8, Vec<u8>), Error>
where
    S: Into<Cow<'a, str>>,

Available on crate features check and alloc only.

Decodes a Crockford Base32Check-encoded string.

Returns

• Ok((u8, Vec<u8>)): The version byte and decoded bytes.
• 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::InvalidDataSize when data requirements are not met.
• Error::TryFromInt when bit arithmetic operations exceeds bounds.

Examples

let encoded = "P7AWVHENJJ0RB441K6JVK5DNJ7J3V5";

// decode string with into a vector
let (version, decoded) = c32::decode_check(encoded)?;

let expected = b"usque ad finem";
assert_eq!(decoded, expected);
assert_eq!(version, 22);
