Function pamoja_scd4x_crc 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_scd4x_crc(
    data: *const u8,
    data_len: usize,
) -> u8

Computes the CRC-8 an SCD4x appends to every data word.

Returns

The checksum over data, or 0 if the pointer is null with a non-zero length.

Safety

data must point to at least data_len readable bytes, or be null when data_len is 0.
