Expand description

Read an bitstring value

To access the content as plain bytes, you will have to interprete the resulting tuple which will contain in its first item the number of padding bits left at the end of the bit string, and in its second item a BitStringObject structure which will, in its sole structure field called data, contain a byte slice representing the value of the bit string which can be interpreted as a big-endian value with the padding bits on the right (as in ASN.1 raw BER or DER encoding).

To access the content as an integer, use the as_u64 or as_u32 methods. Remember that a BER bit string has unlimited size, so these methods return Result or Option objects.
