Module lib::assert_result

Assert macros for Result {Ok, Err}

These macros help compare a Result that is either Ok, Err.

The macros use these capabilities:

• implements .is_ok() -> boolean

• implements .unwrap() -> comparable

• implements .is_err() -> boolean

• implements .unwrap_err() -> comparable

Macros

• assert_result_ok!(a) ≈ a.is_ok()

• assert_result_ok_eq!(a, b) ≈ a.is_ok() & b.is_ok() & a.unwrap() == b.unwrap()

• assert_result_ok_ne!(a, b) ≈ a.is_ok() & b.is_ok() & a.unwrap() != b.unwrap()

• assert_result_err!(a) ≈ a.is_err()

Example

let a: Result<(), i8> = Result::Ok(());
assert_result_ok!(a);

Modules

• assert_result_err
  Assert expression is Err(_).
• assert_result_ok
  Assert expression is Ok(_).
• assert_result_ok_eq
  Assert two expressions are Ok(_) and their values are equal.
• assert_result_ok_ne
  Assert two expressions are Ok(_) and their values are not equal.
