Function rustc_driver_impl::catch_fatal_errors
source · pub fn catch_fatal_errors<F: FnOnce() -> R, R>(
f: F
) -> Result<R, ErrorGuaranteed>
Expand description
Runs a closure and catches unwinds triggered by fatal errors.
The compiler currently unwinds with a special sentinel value to abort
compilation on fatal errors. This function catches that sentinel and turns
the panic into a Result
instead.
