parse_type extends the parse module (opposite of string.format()) with the following features: build type converters for common use cases (enum/mapping, {choice);} build a type converter with a cardinality constraint {(0..1,0..*,1..*);} from the type converter with {cardinality=1.;} compose a type converter from other type {converters;} an extended parser that supports the CardinalityField naming schema and creates missing type variants (0..1,0..*,1..*) from the primary type converter
