Struct OctetStringRef 

pub struct OctetStringRef { /* 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 OctetStringRef

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

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

Errors

Returns Error with ErrorKind::Length in the event slice is too long.

pub fn as_bytes(&self) -> &[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<'a, T: Decode<'a>>(&'a self) -> Result<T, T::Error>

Parse T from this OCTET STRING’s contents.

Errors

Returns T::Error in the event a decoding error occurred.
