Function assert_panic_free::assert_panic_free [−][src]
pub fn assert_panic_free<R, F: FnOnce() -> R>(f: F) -> R
A lightweight higher-order-function that doesn’t compile if a function you pass to it might panic. This probably wont’ work unless you’re compiling your code with optimizations enabled.
Example
works when built with optimizations / release:
assert_panic_free::assert_panic_free(|| 32);
doesn’t work:
ⓘ
assert_panic_free(|| panic!(":("));
