Values

decode

</> 
pub fn decode(
  input: String,
) -> Result(BitArray, encoding.CodecError)

Decode a Crockford Base32 string to a BitArray. Accepts hyphens (ignored). O->0, I/L->1. Case-insensitive.

decode_check

</> 
pub fn decode_check(
  input: String,
) -> Result(BitArray, encoding.CodecError)

Decode a Crockford Base32 string with check symbol verification. The last character is the check symbol; the rest is the encoded data. Returns Error(InvalidChecksum) if the check symbol does not match.

encode

</> 
pub fn encode(data: BitArray) -> String

Encode a BitArray to Crockford Base32 string. The input is treated as a big-endian unsigned integer and converted to base 32 using Crockford’s alphabet.

encode_check

</> 
pub fn encode_check(data: BitArray) -> String

Encode a BitArray to Crockford Base32 with a check symbol appended. The check symbol is computed as the numeric value of the data mod 37, mapped to the 37-character check alphabet (0-9A-Z plus *~$=U).
