Crate abort_on_panic [−] [src]
When calling Rust code from C, it's unsafe to call panic!
. Doing so
may cause unsafe behavior. But when calling user-defined functions,
we sometimes need to enforce these rules.
#[macro_use] extern crate abort_on_panic; #[test] pub fn test_macro() { let result = abort_on_panic!({ "value" }); assert_eq!("value", result); abort_on_panic!("cannot panic inside FFI callbacks", { // ... }); }
Macros

Once this object is created, it can only be destroyed in an orderly fashion. Attempting to clean it up from a panic handler will abort the process. |
