redox::debug_assert_eq!
[−]
( $ ( $ arg : tt ) * ) => ( if cfg ! ( debug_assertions ) { assert_eq ! ( $ ( $ arg ) * ) ; } )
Asserts that two expressions are equal to each other, testing equality in both directions.
On panic, this macro will print the values of the expressions.
Unlike assert_eq!
, debug_assert_eq!
statements are only enabled in non
optimized builds by default. An optimized build will omit all
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.
Examples
let a = 3; let b = 1 + 2; debug_assert_eq!(a, b);
