Struct BytesRef 

pub(crate) struct BytesRef<'a> {
    pub length: Length,
    pub inner: &'a [u8],
}

Byte slice newtype which respects the Length::max() limit.

Fields

length: Length

Precomputed Length (avoids possible panicking conversions)

inner: &'a [u8]

Inner value

Implementations

impl<'a> BytesRef<'a>

pub const EMPTY: Self

Constant value representing an empty byte slice.

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

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

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

Borrow the inner byte slice

pub fn len(self) -> Length

Get the Length of this BytesRef

pub fn is_empty(self) -> bool

Is this BytesRef empty?

Trait Implementations

impl AsRef<[u8]> for BytesRef<'_>

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

impl<'a> Clone for BytesRef<'a>

fn clone(&self) -> BytesRef<'a>

Returns a duplicate of the value.

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

impl<'a> Debug for BytesRef<'a>

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

Formats the value using the given formatter.

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

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

Attempt to decode this message using the provided Reader.

impl Default for BytesRef<'_>

fn default() -> Self

Returns the “default value” for a type.

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<'a> From<&'a StrOwned> for BytesRef<'a>

fn from(s: &'a StrOwned) -> BytesRef<'a>

Converts to this type from the input type.

impl<'a> From<AnyRef<'a>> for BytesRef<'a>

fn from(any: AnyRef<'a>) -> BytesRef<'a>

Converts to this type from the input type.

impl From<BytesRef<'_>> for BytesOwned

fn from(s: BytesRef<'_>) -> BytesOwned

Converts to this type from the input type.

impl<'a> From<StrRef<'a>> for BytesRef<'a>

fn from(s: StrRef<'a>) -> BytesRef<'a>

Converts to this type from the input type.

impl<'a> Ord for BytesRef<'a>

fn cmp(&self, other: &BytesRef<'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.

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

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for BytesRef<'a>

fn eq(&self, other: &BytesRef<'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.

impl<'a> PartialOrd for BytesRef<'a>

fn partial_cmp(&self, other: &BytesRef<'a>) -> 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.

impl<'a> RefToOwned<'a> for BytesRef<'a>

type Owned = BytesOwned

The resulting type after obtaining ownership.

fn ref_to_owned(&self) -> Self::Owned

Creates a new object taking ownership of the data

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

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
