Function der_parser::der::parse_der_bitstring [−][src]
pub fn parse_der_bitstring(i: &[u8]) -> DerResult<'_>
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.
