Structs

• ParallelGuard
  A guard used to hold panics that occur during a parallel section to later by unwound. This is used for the parallel compiler to prevent fatal errors from non-deterministically hiding errors by ensuring that everything in the section has completed executing before continuing with unwinding. It’s also used for the non-parallel code to ensure error message output match the parallel compiler for testing purposes.

Functions

• parallel_guard
  This gives access to a fresh parallel guard in the closure and will unwind any panics caught in it after the closure returns.
