Macro more_asserts::debug_assert_le [−][src]
macro_rules! debug_assert_le {
($($arg : tt) +) => { ... };
}
Expand description
Same as assert_le!
in debug builds or release builds where the
-C debug-assertions
was provided to the compiler. For all other builds,
vanishes without a trace.
Optionally may take an additional message to display on failure, which is formatted using standard format syntax.
Example
#[macro_use]
extern crate more_asserts;
fn main() {
// These are compiled to nothing if debug_assertions are off!
debug_assert_le!(4, 4);
debug_assert_le!(4, 5);
debug_assert_le!(4, 5, "With a message");
debug_assert_le!(4, 4, "With a formatted message: {}", "oh no");
}
