Function std::panicking::__rust_start_panic[][src]

unsafe extern "C-unwind" fn __rust_start_panic(
    payload: *mut &mut dyn BoxMeUp
) -> u32
Expand description

payload is passed through another layer of raw pointers as &mut dyn Trait is not FFI-safe. BoxMeUp lazily performs allocation only when needed (this avoids allocations when using the “abort” panic runtime).
