Struct OctetString 

pub struct OctetString { /* private fields */ }

ASN.1 OCTET STRING type: owned form.

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

This type provides the same functionality as OctetStringRef but owns the backing data.

Implementations

impl OctetString

pub fn new(bytes: impl Into<Box<[u8]>>) -> Result<Self, Error>

Create a new ASN.1 OCTET STRING.

Errors

If bytes is too long.

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

Borrow the inner byte slice.

pub fn into_bytes(self) -> Box<[u8]>

Take ownership of the octet string.

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?

Trait Implementations

impl AsRef<[u8]> for OctetString

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<OctetStringRef> for OctetString

fn borrow(&self) -> &OctetStringRef

Immutably borrows from an owned value.

impl Clone for OctetString

fn clone(&self) -> OctetString

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OctetString

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for OctetString

type Error = Error

Type returned in the event of a decoding error.

fn decode_value<R: Reader<'a>>( reader: &mut R, header: Header, ) -> Result<Self, Error>

Attempt to decode this value using the provided Reader.

impl EncodeValue for OctetString

fn value_len(&self) -> Result<Length, Error>

Compute the length of this value (sans Tag+Length header) when encoded as ASN.1 DER.

fn encode_value(&self, writer: &mut impl Writer) -> Result<(), Error>

Encode value (sans Tag+Length header) as ASN.1 DER using the provided Writer.

fn header(&self) -> Result<Header>

where Self: Tagged,

Get the Header used to encode this value.

impl FixedTag for OctetString

const TAG: Tag = Tag::OctetString

ASN.1 tag

impl<'a> From<&'a OctetString> for &'a OctetStringRef

fn from(octet_string: &'a OctetString) -> &'a OctetStringRef

Converts to this type from the input type.

impl From<&OctetStringRef> for OctetString

fn from(octet_string_ref: &OctetStringRef) -> OctetString

Converts to this type from the input type.

impl From<OctetString> for Vec<u8>

fn from(octet_string: OctetString) -> Vec<u8>

Converts to this type from the input type.

impl Ord for OctetString

fn cmp(&self, other: &OctetString) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OctetString

fn eq(&self, other: &OctetString) -> 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.

impl PartialOrd for OctetString

fn partial_cmp(&self, other: &OctetString) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: &'__der Any) -> Result<OctetString>

Performs the conversion.

impl<'__der> TryFrom<AnyRef<'__der>> for OctetString

type Error = Error

The type returned in the event of a conversion error.
