Struct json_ld_core::loader::none::NoLoader

source · [−]

pub struct NoLoader<I = Index, M = Location<I>, T = Value<M>>(_);

Expand description

Dummy loader.

A dummy loader that does not load anything. Can be useful when you know that you will never need to load remote resource.

Raises an LoadingDocumentFailed at every attempt to load a resource.
