Struct OwlLiteral 

pub struct OwlLiteral<Text = String>
where
    Text: Bos<str> + AsRef<str>,
{ /* private fields */ }

A standard RDF literal with an exact UTF-8 lexical form.

Equality is RDF term equality, not datatype value equality. Ill-typed lexical forms are representable; evaluating datatype lexical spaces is a separate task.

Implementations

impl<Text> Literal<Text>

where Text: Bos<str> + AsRef<str>,

pub fn try_new( lexical: Text, metadata: LiteralMetadata<Text>, ) -> Result<Literal<Text>, ModelError>

Validate standard RDF datatype/facet combinations without evaluating lexical values.

Errors

Returns ModelError::InconsistentLiteralFacets for inconsistent metadata.

pub fn lexical(&self) -> &str

The exact lexical form, without value normalization.

pub const fn metadata(&self) -> &LiteralMetadata<Text>

Metadata accessible without copying the lexical payload.

impl Literal

pub fn typed( lexical: impl Into<String>, datatype: Iri<String>, ) -> Result<Literal, ModelError>

Construct a non-language typed literal.

Errors

Language datatypes require their corresponding facets and are rejected here.

pub fn string(lexical: impl Into<String>) -> Literal

Construct an XML Schema string literal.

pub fn language_tagged( lexical: impl Into<String>, language: LanguageTag, ) -> Literal

Construct a language-tagged literal from a validated tag.

pub fn directional( lexical: impl Into<String>, language: LanguageTag, direction: BaseDirection, ) -> Literal

Construct a directional language-tagged literal from a validated tag.

pub fn as_ref(&self) -> Literal<&str>

Borrow the lexical form and metadata without copying their text.
