Struct rustc_data_structures::sync::parallel::ParallelGuard

source ·

pub struct ParallelGuard {
    panic: Mutex<Option<IntoDynSyncSend<Box<dyn Any + Send + 'static>>>>,
}

Expand description

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.
