Struct StrRef 

pub struct StrRef<'a> {
    pub(crate) inner: &'a str,
    pub(crate) length: Length,
}

String slice newtype which respects the Length::max limit.

Fields

inner: &'a str

Inner value

length: Length

Precomputed Length (avoids possible panicking conversions)

Implementations

impl<'a> StrRef<'a>

pub fn new(s: &'a str) -> Result<Self>

Create a new StrRef, ensuring that the byte representation of the provided str value is shorter than Length::max().

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

Parse a StrRef from UTF-8 encoded bytes.

pub fn as_str(&self) -> &'a str

Borrow the inner str

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

Borrow the inner byte slice

pub fn len(self) -> Length

Get the Length of this StrRef

pub fn is_empty(self) -> bool

Is this StrRef empty?

Trait Implementations

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

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

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

impl AsRef<str> for StrRef<'_>

fn as_ref(&self) -> &str

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

impl<'a> Clone for StrRef<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for StrRef<'a>

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

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for StrRef<'a>

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

Attempt to decode this message using the provided Reader.

impl<'a> EncodeValue for StrRef<'a>

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<StrRef<'_>> for BytesOwned

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

Converts to this type from the input type.

impl From<StrRef<'_>> for StrOwned

fn from(s: StrRef<'_>) -> StrOwned

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 StrRef<'a>

fn cmp(&self, other: &StrRef<'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 StrRef<'a>

fn eq(&self, other: &StrRef<'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 StrRef<'a>

fn partial_cmp(&self, other: &StrRef<'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 StrRef<'a>

type Owned = StrOwned

The resulting type after obtaining ownership.

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

Creates a new object taking ownership of the data
