Macro assertables::assert_lt

macro_rules! assert_lt {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($arg:tt)+) => { ... };
}

Assert one value is less than another value.

• When true, return ().

• Otherwise, call panic! with a message and the values of the expressions with their debug representations.

Examples

assert_lt!(1, 2);
//-> ()

// assert_lt!(2, 1);
//-> panic!("assertion failed: `assert_lt(left, right)`\n  left: `2`\n right: `1`")

This macro has a second form where a custom message can be provided.
