Struct der::asn1::OctetStringRef

pub struct OctetStringRef<'a> { /* private fields */ }

ASN.1 OCTET STRING type: borrowed form.

Octet strings represent contiguous sequences of octets, a.k.a. bytes.

This is a zero-copy reference type which borrows from the input data.

Implementations

impl<'a> OctetStringRef<'a>

pub fn new(slice: &'a [u8]) -> Result<Self>

Create a new ASN.1 OCTET STRING from a byte slice.

pub fn as_bytes(&self) -> &'a [u8]

Borrow the inner byte slice.

pub fn len(&self) -> Length

Get the length of the inner byte slice.

pub fn is_empty(&self) -> bool

Is the inner byte slice empty?

pub fn decode_into<T: Decode<'a>>(&self) -> Result<T>

Parse T from this OCTET STRING’s contents.

impl<'a> Ord for OctetStringRef<'a>

fn cmp(&self, other: &OctetStringRef<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
