Enum UnwindTerminateReason

source 
pub enum UnwindTerminateReason {
    Abi,
    InCleanup,
}
🔬This is a nightly-only experimental API. (custom_mir)
Expand description

The reason we are terminating the process during unwinding.

Variants§

§

Abi

🔬This is a nightly-only experimental API. (custom_mir)

Unwinding is just not possible given the ABI of this function.

§

InCleanup

🔬This is a nightly-only experimental API. (custom_mir)

We were already cleaning up for an ongoing unwind, and a second, nested unwind was triggered by the drop glue.
