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.


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");
