Struct OctetStringRef 

pub struct OctetStringRef<'a> {
    inner: BytesRef<'a>,
}

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.

Fields

inner: BytesRef<'a>

Inner value

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.

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

where Self: Sized,

impl<'a> PartialEq for OctetStringRef<'a>

fn eq(&self, other: &OctetStringRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
