Macro assertables::assert_io_le

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

Assert a value is less than or equal to another.

• When true, return ().

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

Examples

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

assert_io_le!(2, 1);
//-> panic!
// assertion failed: `assert_io_le!(left, right)`
//   left: `2`,
//  right: `1`

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