Prevent your panics from unwinding past FFI boundaries with this one simple trick!
Intended to be used in place of #[unwind(aborts)]
until it is stabilized.
Add this to your [dependencies]
in Cargo.toml
:
unwind_aborts = "0.1.0"
Annotate your functions with #[unwind_aborts]
to catch stack unwinding and
abort the process instead:
use unwind_aborts::unwind_aborts;
#[unwind_aborts]
pub extern fn foo() {
panic!("this is safe");
}
The example above is equivalent to:
pub extern fn foo() {
let result = std::panic::catch_unwind(|| {
panic!("this is safe");
});
match result {
Ok(x) => x,
Err(_) => std::process::abort(),
}
}
