Function rdf_canon::api::canonicalize_graph_with

pub fn canonicalize_graph_with<D: Digest>(
    input_graph: &Graph,
    options: &CanonicalizationOptions
) -> Result<String, CanonicalizationError>

Given some options (e.g., call limit), returns the serialized canonical form of the canonicalized dataset, where any blank nodes in the input graph are assigned deterministic identifiers.
