Crate abort_on_panic [−] [src]
Current status
This crate is mostly obsolete. For almost all use cases, you should
instead add the following to your Cargo.toml
file:
[profile]
panic = 'abort'
Original documentation
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.
⚠Be careful when using this code, it's not being tested!
#[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
