Struct Context

pub struct Context<T = IriBuf, B = BlankIdBuf> { /* private fields */ }

Processed JSON-LD context.

Represents the result of the context processing algorithm implemented by the json-ld-context-processing crate.

Implementations

impl<T, B> Context<T, B>

pub fn previous_context(&self) -> Option<&Context<T, B>>

Returns a reference to the previous context.

pub fn len(&self) -> usize

Returns the number of terms defined.

pub fn is_empty(&self) -> bool

Checks if no terms are defined.

pub fn definitions(&self) -> &Definitions<T, B>

Returns a handle to the term definitions.

pub fn has_protected_items(&self) -> bool

Checks if the context has a protected definition.

pub fn inverse(&self) -> &InverseContext<T, B>

where T: Clone + Hash + Eq, B: Clone + Hash + Eq,

Returns the inverse of this context.

pub fn set_normal( &mut self, key: Key, definition: Option<NormalTermDefinition<T, B>>, ) -> Option<NormalTermDefinition<T, B>>

Sets the normal definition for the given term key.

pub fn set_type( &mut self, type_: Option<TypeTermDefinition>, ) -> Option<TypeTermDefinition>

Sets the @type definition.

pub fn set_base_iri(&mut self, iri: Option<T>)

Sets the base IRI.

pub fn set_vocabulary(&mut self, vocab: Option<Term<T, B>>)

Sets the @vocab value.

pub fn set_default_language(&mut self, lang: Option<LenientLangTagBuf>)

Sets the default @language value.

pub fn set_default_base_direction(&mut self, dir: Option<Direction>)

Sets the default @direction value.

pub fn set_previous_context(&mut self, previous: Context<T, B>)

Sets the previous context.

pub fn into_syntax_definition( self, vocabulary: &impl Vocabulary<Iri = T, BlankId = B>, ) -> Definition

Converts this context into its syntactic definition.

pub fn map_ids<U, C>( self, map_iri: impl FnMut(T) -> U, map_id: impl FnMut(Id<T, B>) -> Id<U, C>, ) -> Context<U, C>

Trait Implementations

impl<T, B> Clone for Context<T, B>

where T: Clone, B: Clone,

fn clone(&self) -> Context<T, B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, B> Default for Context<T, B>

fn default() -> Context<T, B>

Returns the “default value” for a type.

impl<T, B> IntoSyntax<T, B> for Context<T, B>

where B: Clone,

fn into_syntax( self, vocabulary: &impl Vocabulary<Iri = T, BlankId = B>, ) -> Context

impl<T, B> PartialEq for Context<T, B>

where T: PartialEq, B: PartialEq,

fn eq(&self, other: &Context<T, B>) -> 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.
