Macro assertables::assume_io_eq

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

Assume one value is 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.

Examples

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

let x = assume_io_eq!(1, 2);
//-> Err(
//       std::io::Error::new(
//           std::io::ErrorKind::InvalidInput, 
//           "assumption failed: `assume_io_eq(left, right)`\n  left: `1`\n right: `2`")]
//       )
//   )

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