[−][src]Struct bcder::int::Unsigned
A BER encoded unsigned integer.
As integers are variable length in BER, this type is just a simple wrapper
atop the underlying Bytes
value containing the raw content. It
guarantees that the wrapped integer is greater or equal to 0. This equals
an integer defined as INTEGER (0..MAX)
in ASN.1.
If you need a integer without any restrictions, you can use Integer
. If
you have even stricter range restrictions, you can also use the methods
provided on the content types to decode into Rust’s primitive integer
types such as u16
.
BER Encoding
In BER, an INTEGER is encoded as a primitive value with the content octets providing a variable-length, big-endian, two‘s complement byte sequence of that integer. Thus, the most-significant bit of the first octet serves as the sign bit and, for an unsigned integer, has to be unset.
