[−][src]Macro chek::debug_unreachable
Panics if reached. This is a variant of the standard library's unreachable!
macro that is controlled by cfg!(debug_assertions)
.
Same as prelude's unreachable!
in debug builds or release builds where the
-C debug-assertions
was provided to the compiler. For all other builds,
vanishes without a trace.
Example
// You probably wouldn't actually use this here let mut value = 0.5; if value < 0.0 { chek::debug_unreachable!("Value out of range {}", value); value = 0.0; }
