Macro std::debug_assert_ne 1.13.0[−][src]
macro_rules! debug_assert_ne { ( $ ( $ arg : tt ) * ) => { ... }; }
Asserts that two expressions are not equal to each other.
On panic, this macro will print the values of the expressions with their debug representations.
Unlike assert_ne!, debug_assert_ne! statements are only enabled in non
optimized builds by default. An optimized build will omit all
debug_assert_ne! statements unless -C debug-assertions is passed to the
compiler. This makes debug_assert_ne! useful for checks that are too
expensive to be present in a release build but may be helpful during
development.
Examples
let a = 3; let b = 2; debug_assert_ne!(a, b);Run
