Module lib::assert_ok

Assert macros for Ok(_) items.

These macros help compare Ok(…) items, such as std::Result::Ok or similar.

Assert expression is Ok(_):

• assert_ok!(a) ≈ a is Ok(_)

Compare Ok(…) to another Ok(…):

• assert_ok_eq!(a, b) ≈ (a ⇒ Ok(a̅) ⇒ a̅) = (b ⇒ Ok(b̅) ⇒ b̅)

• assert_ok_ne!(a, b) ≈ (a ⇒ Ok(a̅) ⇒ a̅) ≠ (b ⇒ Ok(b̅) ⇒ b̅)

Compare Ok(…) to an expression:

• assert_ok_eq_expr!(a, expr) ≈ (a ⇒ Ok(a̅) ⇒ a̅) = b

• assert_ok_ne_expr!(a, b) ≈ (a ⇒ Ok(a̅) ⇒ a̅) ≠ b

Example

use assertables::*;
 
let a: Result<(), i8> = Ok(());
assert_ok!(a);
