SchemaPartition

A structure indicating the match result of running Schema#partition against a given predicate

• if the schema is not of a structure, or if none of the fields matched, then NoMatch should be returned
• if the schema is a structure and only a subset of its fields pass the predicate, then PartialMatch should be returned
• if the schema is a structure and all of its fields pass the predicate, then TotalMatch should be returned
