Function construct_codewords 

pub fn construct_codewords(
    rawbits: &[u8],
    version: Version,
    ec_level: EcLevel,
) -> QrResult<(Vec<u8>, Vec<u8>)>

Constructs data and error correction codewords ready to be put in the QR code matrix.

Errors

Returns Err(QrError::InvalidVersion) if it is not valid to use the ec_level for the given version (e.g. Version::Micro(1) with EcLevel::H).

Returns QrError::InvalidDataLength if rawbits does not contain exactly the padded data bytes required by this version and correction level. For Micro M1 and M3, this includes the byte containing the final half codeword.
