Variants

`Literal(Literal<J>, Option<T>)`

Tuple Fields

0: Literal<J>

1: Option<T>

Typed literal value.

`LangString(LangString<J>)`

Tuple Fields

0: LangString<J>

Language tagged string.

`Json(J)`

Tuple Fields

0: J

JSON literal value.

Implementations

source

pub fn typ(&self) -> Option<Type<&T>>

Return the type of the value if any.

This will return Some(Type::Json) for JSON literal values.

source

pub fn language(&self) -> Option<LenientLanguageTag<'_>>

If the value is a language tagged string, return its associated language if any.

Returns None if the value is not a language tagged string.

source

pub fn direction(&self) -> Option<Direction>

If the value is a language tagged string, return its associated direction if any.

Returns None if the value is not a language tagged string.
