Context document loader.

This is a subclass of loaders able to extract a local context from a loaded JSON-LD document.

It is implemented for any loader where the output type implements ExtractContext.

Required Associated Types

type Context

Output of the loader, a context.

type ContextError

Error type.

Required Methods

fn load_context_with<'a>(
    &'a mut self,
    vocabulary: &'a mut impl Send + Sync + IriVocabularyMut<Iri = I>,
    url: I
) -> Pin<Box<dyn Future<Output = Result<RemoteDocument<I, M, Self::Context>, Self::ContextError>> + Send + 'a, Global>>where
    I: 'a,
    M: 'a,

Loads the context behind the given IRI, using the given vocabulary.

Provided Methods

fn load_context<'a>(
    &'a mut self,
    url: I
) -> Pin<Box<dyn Future<Output = Result<RemoteDocument<I, M, Self::Context>, Self::ContextError>> + Send + 'a, Global>>where
    I: 'a,
    M: 'a,
    (): IriVocabulary<Iri = I>,

Loads the context behind the given IRI.

Implementors

impl<I, M, L> ContextLoader<I, M> for Lwhere
    I: Send,
    L: Loader<I, M>,
    <L as Loader<I, M>>::Output: ExtractContext<M>,

type Context = <<L as Loader<I, M>>::Output as ExtractContext<M>>::Context

type ContextError = ContextLoaderError<<L as Loader<I, M>>::Error, <<L as Loader<I, M>>::Output as ExtractContext<M>>::Error>
