priority
The priority of this type mapper used for ordering during mapper resolution.
Mappers with higher priority values are consulted first when the registry searches for a suitable mapper. This allows more specific or custom mappers to override default implementations. The default priority is 0.
Common priority ranges:
High priority (0.5+, 1.]: Custom user mappers that should override defaults
Standard priority (0., 0.5]: Priority of default Exposed type mappers
Default priority (0.)
Return
The priority value, with higher values indicating higher priority
