Macro assertables::assume_lt

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

Assume one value is less than another value.

• When true, return Ok(true).

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

Example

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

let x = assume_lt!(2, 1);
//-> Err("assumption failed: `assume_lt(left, right)`\n  left: `2`\n right: `1`")

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