Last updated 3 years ago

Overview

  • Burst is an LLVM based math-aware backend Compiler Technology. It takes the C# jobs and produces highly-optimized code taking advantage of the particular capabilities of the platform.

  • Burst is primarily designed to work efficiently with the Job system.

  • Burst is working on a subset of .NET that doesn't allow the usage of any managed objects/reference types in your code (class in C#).

  • Supports a .

Language Support

Unsupported features:

  • Types:

    • char (this will be supported in a future release)

    • string as this is a managed type

    • decimal

  • Managed arrays: You should use instead a native container, NativeArray<T> for instance.

  • catch

  • try/finally (which will come at some point)

  • foreach as it is requiring try/finally (This should be supported in a future version)

  • Storing to static fields except via Shared Static

  • Any methods related to managed objects (e.g string methods...etc.)
