pub fn load_root_schema_from_ref(
schema_ref: &str,
instance_parent: &Path,
) -> Result<(RootSchema, String)>Expand description
Loads a root schema from a $schema reference: http/https/file URLs via load_external_schema,
otherwise as a filesystem path (relative paths are resolved against instance_parent).
Returns the loaded schema and a URI string suitable for RootSchema::cache_key fallback / preloaded map keys
(matches base_uri after load).
