Implementations

impl BytesRef

pub const EMPTY: &'static Self

Constant value representing an empty byte slice.

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

Create a new BytesRef, ensuring that the provided slice value is shorter than Length::MAX.

pub(crate) const fn new_unchecked(slice: &[u8]) -> &Self

Perform a raw conversion of a byte slice to Self without first performing a length check.

pub(crate) const fn as_ptr(&self) -> *const BytesRef

Get a pointer to this BytesRef.

pub const fn as_slice(&self) -> &[u8]

Borrow the inner byte slice

pub fn len(&self) -> Length

Get the Length of this BytesRef.

pub const fn is_empty(&self) -> bool

Is this BytesRef empty?

pub fn prefix(&self, length: Length) -> Result<&Self>

Get a prefix of a [crate::bytes_ref::BytesRef] of the given length.

impl Borrow<BytesRef> for BytesOwned

fn borrow(&self) -> &BytesRef

Immutably borrows from an owned value.

impl Debug for BytesRef

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

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for &'a BytesRef

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>

Attempt to decode this value using the provided Reader.

impl DerOrd for BytesRef

fn der_cmp(&self, other: &Self) -> Result<Ordering>

Return an Ordering between self and other when serialized as ASN.1 DER.

impl EncodeValue for BytesRef

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

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<()>

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

impl From<&BytesRef> for BytesOwned

fn from(bytes: &BytesRef) -> BytesOwned

impl Hash for BytesRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

impl Ord for BytesRef

fn cmp(&self, other: &BytesRef) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for BytesRef

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

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.

impl ToOwned for BytesRef

type Owned = BytesOwned

The resulting type after obtaining ownership.

fn to_owned(&self) -> BytesOwned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.

impl<'a> TryFrom<&'a [u8]> for &'a BytesRef

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
