[−][src]Struct bcder::int::Unsigned

pub struct 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.
