Macro assertables::assure_ne

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

Assure two values are not equal.

• 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_ne!(1, 2);
//-> Ok(true)

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

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