Assure one value is less than or equal to another value.

• When true, return Ok(true).

• When false, return Ok(false).

• Otherwise, return Err with a message and the values of the expressions with their debug representations.

Example

let x = assure_io_le!(1, 2);
//-> Ok(true)

let x = assure_io_le!(2, 1);
//-> Ok(false)

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