Job extensions

The Unity C# job system lets you run code on multiple threads. The system provides scheduling, parallel processing, and multi-threaded safety. The job system is a core Unity module that provides the general purpose interfaces and classes to create and run jobs (whether or not you are using ECS).

These interfaces include:

• IJob: Create a job that runs on any thread or core, which the job system scheduler determines.
• IJobParallelFor: Create a job that can run on multiple threads in parallel to process the elements of a NativeContainer.
• IJobExtensions: Provides extension methods to run IJobs.
• IJobParalllelForExtensions: Provides extension methods to run IJobParallelFor jobs.
• JobHandle: A handle to access a scheduled job. You can also use JobHandle instances to specify dependencies between jobs.

For an overview of the jobs system see C# Job System in the Unity User Manual.

The Jobs package extends the job system to support ECS. It contains:

• IJobParallelForDeferExtensions
• IJobParallelForFilter
• JobParallelIndexListExtensions
• Job​Struct​Produce<T>
