Macro gstd::prelude::debug_assert_eq

macro_rules! debug_assert_eq {
    ($($arg:tt)*) => { ... };
}

Asserts that two expressions are equal to each other.

On panic, this macro will print the values of the expressions with their debug representations.

Unlike assert_eq!, debug_assert_eq! statements are only enabled in non optimized builds by default. An optimized build will not execute debug_assert_eq! statements unless -C debug-assertions is passed to the compiler. This makes debug_assert_eq! useful for checks that are too expensive to be present in a release build but may be helpful during development. The result of expanding debug_assert_eq! is always type checked.

Examples

let a = 3;
let b = 1 + 2;
debug_assert_eq!(a, b);
