macro_rules! debug_assert_command_stderr_eq_expr { ($($arg:tt)*) => { ... }; }
Expand description
Assert a command stderr string is equal to an expression.
This macro provides the same statements as assert_command_stderr_eq_expr,
except this macro’s statements are only enabled in non-optimized
builds by default. An optimized build will not execute this macro’s
statements unless -C debug-assertions is passed to the compiler.
This macro is useful for checks that are too expensive to be present in a release build but may be helpful during development.
The result of expanding this macro is always type checked.
An unchecked assertion allows a program in an inconsistent state to
keep running, which might have unexpected consequences but does not
introduce unsafety as long as this only happens in safe code. The
performance cost of assertions, however, is not measurable in general.
Replacing assert*! with debug_assert*! is thus only encouraged
after thorough profiling, and more importantly, only in safe code!
This macro is intendend to work in a similar way to
std::debug_assert.
