Gathers and caches reflection data for the internal job system's managed bindings. Unity is responsible for calling this method - don't call it yourself.
When the Jobs package is included in the project, Unity generates code to call EarlyJobInit at startup. This results in the following benefits: Job initialization doesn't lazily occur during job scheduling, which would increase the time it takes to schedule a job. Burst compiled code may schedule jobs because the reflection part of initialization, which is not compatible with burst compiler constraints, has already happened in EarlyJobInit. Note: While the Jobs package code generator handles this automatically for all closed job types, you must register those with generic arguments (like IJobFor<MyJobType<T>>) manually for each specialization with Unity.Jobs.RegisterGenericJobTypeAttribute.
