Struct json_ld::FsLoader

pub struct FsLoader<I = IriIndex> { /* private fields */ }

File-system loader.

This is a special JSON-LD document loader that can load document from the file system by attaching a directory to specific URLs.

Loaded documents are not cached: a new file system read is made each time an URL is loaded even if it has already been queried before.
