NoAutoStaticsCleanupAttribute

Description

Prevents static variables from being automatically reset on entering or exiting Play mode with domain reload disabled.

This attribute can be applied to classes, structs, fields, properties, and events. Applying it to a class or struct ensures all static members of the class or struct are not reset. For more information, refer to Enter Play mode with domain reload disabled in the manual.
