Struct StringLiteralRef 

pub struct StringLiteralRef<'value>(pub &'value str, pub Option<&'value str>);

A reference to a string literal in RDF, consisting of a value and an optional language tag.

This struct provides a borrowed view of a string literal.

Tuple Fields

0: &'value str

1: Option<&'value str>

Implementations

impl StringLiteralRef<'_>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Trait Implementations

impl<'value> Clone for StringLiteralRef<'value>

fn clone(&self) -> StringLiteralRef<'value>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'value> Debug for StringLiteralRef<'value>

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

Formats the value using the given formatter.

impl Ord for StringLiteralRef<'_>

fn cmp(&self, other: &StringLiteralRef<'_>) -> 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<'value> PartialEq for StringLiteralRef<'value>

fn eq(&self, other: &StringLiteralRef<'value>) -> 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 StringLiteralRef<'_>

fn partial_cmp(&self, other: &StringLiteralRef<'_>) -> 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> TryFrom<TypedValueRef<'a>> for StringLiteralRef<'a>

type Error = ThinError

The type returned in the event of a conversion error.

fn try_from( value: TypedValueRef<'a>, ) -> Result<StringLiteralRef<'a>, <StringLiteralRef<'a> as TryFrom<TypedValueRef<'a>>>::Error>

Performs the conversion.
