Struct 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.

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

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
