BurstCompiler

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 subset of C#.

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.)
