Function der_parser::parse_der_integer
[−]
[src]
pub fn parse_der_integer(i: &[u8]) -> IResult<&[u8], DerObject>
Read an integer value
The encoding of a boolean value shall be primitive. The contents octets shall consist of one or more octets.
To access the content, use the as_u64
,
as_u32
,
as_biguint
or
as_bigint
methods.
Remember that a DER integer has unlimited size, so these methods return Result
or Option
objects.
Examples
let empty = &b""[..]; let bytes = [0x02, 0x03, 0x01, 0x00, 0x01]; let expected = DerObject::from_obj(DerObjectContent::Integer(b"\x01\x00\x01")); assert_eq!( parse_der_integer(&bytes), IResult::Done(empty, expected) );
