Struct StringRef 

#[repr(transparent)]
pub struct StringRef(str);

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

Tuple Fields

0: str

Implementations

impl StringRef

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

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

pub(crate) const fn new_unchecked(s: &str) -> &Self

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

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

Parse a StringRef from UTF-8 encoded bytes.

pub fn as_str(&self) -> &str

Borrow the inner str.

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

Borrow the inner byte slice.

pub fn len(&self) -> Length

Get the Length of this StringRef.

pub fn is_empty(&self) -> bool

Is this StringRef empty?

Trait Implementations

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

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

impl AsRef<BytesRef> for StringRef

fn as_ref(&self) -> &BytesRef

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

impl AsRef<StringRef> for StringOwned

fn as_ref(&self) -> &StringRef

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

impl AsRef<str> for StringRef

fn as_ref(&self) -> &str

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

impl Borrow<StringRef> for StringOwned

fn borrow(&self) -> &StringRef

Immutably borrows from an owned value.

impl Debug for StringRef

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

Formats the value using the given formatter.

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

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 EncodeValue for StringRef

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 Hash for StringRef

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

Feeds this value into the given Hasher.

impl Ord for StringRef

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

This method returns an Ordering between self and other.

impl PartialEq for StringRef

fn eq(&self, other: &StringRef) -> 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 StringRef

fn partial_cmp(&self, other: &StringRef) -> 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 ToOwned for StringRef

type Owned = StringOwned

The resulting type after obtaining ownership.

fn to_owned(&self) -> StringOwned

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 Eq for StringRef
