| [CompileSynchronously](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/compilesynchronously.md) | Gets or sets whether or not to Burst compile the code immediately on first use, or in the background over time.                                                                                                                                                                       |
| [Debug](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/debug.md)                               | Gets or sets whether to compile the code in a way that allows it to be debugged. If this is set to `true`, the current implementation disables optimisations on this method allowing it to be debugged using a Native debugger.                                                       |
| [DisableDirectCall](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/disabledirectcall.md)       | Gets or sets a boolean to disable the translation of a static method call as direct call to the generated native method. By default, when compiling static methods with Burst and calling them from C#, they will be translated to a direct call to the Burst generated method. code. |
| [DisableSafetyChecks](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/disablesafetychecks.md)   | Gets or sets whether to disable safety checks for the current job or function pointer. If this is set to `true`, the current job or function pointer will be compiled with safety checks disabled unless the global 'Safety Checks/Force On' option is active.                        |
| [FloatMode](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/floatmode.md)                       | Gets or sets the float mode of operation for this Burst compilation.                                                                                                                                                                                                                  |
| [FloatPrecision](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/floatprecision.md)             | Gets or sets the floating point precision to use for this Burst compilation. Allows you to trade accuracy for speed of computation, useful when you don't require much precision.                                                                                                     |
| [OptimizeFor](/engine/6000.7/script-reference/unity/burst/burstcompileattribute/optimizefor.md)                   | How should this entry-point be optimized.                                                                                                                                                                                                                                             |
