Macro assertables::assertable_io_ne

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

Assert one value is not equal to another value.

• When true, return Ok(()).

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

Examples

let x = assertable_io_ne!(1, 2);
//-> Ok(())
assert!(x.is_ok());

let x = assertable_io_ne!(1, 1);
//-> Err(std::io::Error::new(std::io::ErrorKind::InvalidInput, "…");
// assertable failed: `assertable_io_ne!(left, right)`
//   left: `1`,
//  right: `1`
assert_eq!(
    x.unwrap_err().get_ref().unwrap().to_string(),
    "assertable failed: `assertable_io_ne!(left, right)`\n  left: `1`,\n right: `1`"
);

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