Enum json_ld::Value

pub enum Value<T = IriBuf, M = ()> {
    Literal(Literal, Option<T>),
    LangString(LangString),
    Json(Meta<Value<M>, M>),
}

Value object.

Either a typed literal value, or an internationalized language string.

Variants

Literal(Literal, Option<T>)

Typed literal value.

LangString(LangString)

Language tagged string.

Json(Meta<Value<M>, M>)

JSON literal value.

Implementations

impl<T, M> Value<T, M>

pub fn as_str(&self) -> Option<&str>

pub fn as_literal(&self) -> Option<(&Literal, Option<&T>)>

pub fn literal_type(&self) -> Option<&T>

pub fn set_literal_type(&mut self, ty: Option<T>) -> Option<T>

Set the literal value type, and returns the old type.

Has no effect and return None if the value is not a literal value.

pub fn map_literal_type<F>(&mut self, f: F)where
    F: FnOnce(Option<T>) -> Option<T>,

Maps the literal value type.

Has no effect if the value is not a literal value.

pub fn as_bool(&self) -> Option<bool>

pub fn as_number(&self) -> Option<&Number>

pub fn typ(&self) -> Option<TypeRef<'_, T>>

Return the type of the value if any.

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

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.

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.

pub fn entries(&self) -> Entries<'_, T, M>

pub fn canonicalize_with(&mut self, buffer: &mut Buffer)

Puts this value object literal into canonical form using the given buffer.

The buffer is used to compute the canonical form of numbers.

pub fn canonicalize(&mut self)

Puts this literal into canonical form.
