Implementations

impl Value<'_>

pub fn unescape(&self) -> Result<Cow<'_, str>, Error>

Return the unescaped value using UTF-8 encoding.

Errors

Throws an error if the value could not be unescaped.

pub fn unescape_with<'entity>( &self, resolve_entity: impl FnMut(&str) -> Option<&'entity str>, ) -> Result<Cow<'_, str>, Error>

Return the unescaped value using UTF-8 encoding and the passed function to resolve the escaped string.

For details see unescape_with.

Errors

Throws an error if the value could not be unescaped.

pub fn decode_and_unescape( &self, encoding: &'static Encoding, ) -> Result<Cow<'_, str>, Error>

Decodes and unescape the value using the passed encoding.

Errors

Throws an error if the value could not be unescaped.

pub fn decode_and_unescape_with<'entity>( &self, encoding: &'static Encoding, resolve_entity: impl FnMut(&str) -> Option<&'entity str>, ) -> Result<Cow<'_, str>, Error>

Return the unescaped value using the passed encoding and the passed function to resolve the escaped string.

For details see unescape_with.

Errors

Throws an error if the value could not be unescaped.

Trait Implementations

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

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

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

impl Borrow<[u8]> for Value<'_>

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

Immutably borrows from an owned value.

impl<'a> Clone for Value<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value<'_>

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

Formats the value using the given formatter.

impl<'a> Hash for Value<'a>

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for Value<'a>

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

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

fn partial_cmp(&self, other: &Value<'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.
