Macro assertables::assert_io_lt[][src]

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

Assert one value is less than another value.

  • When true, return Ok(true).

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

Examples

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

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