An implementation of the abort function that works without the standard library.
Provides an AbortGuard type to abort the process unless explicitly "defused".
This can prevent panics from unwinding in the middle of unsafe code,
which trivially makes the code exception safe.
The library offers multiple possible implementations, which can be controlled by using feature flags.
- Using the Rust standard library
std::process::abortfunction. This is enabled by using the "std" feature (disabled by default). - Using the C standard library
abortfunction from thelibccrate. This requires linking against the C standard library, but not the Rust one. This is enabled by using the "libc" feature (disabled by default). - If the
panic!implementation is known to abort instead of unwinding, then theabortfunction simply triggers a panic. This requires a recent version of Rust (1.60) in order to detect whether panics unwind or abort. - On Rust versions since 1.81, this unwinds past a
extern "C"function, which is guaranteed to trigger an abort. - If no other implementations are available,
then the
abortfunction triggers a double-panic. This always triggers an abort regardless of the rust version or compiler settings.
