Module assert_some

Assert for Some(_) items.

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

Assert expression is Some:

• assert_some!(a) ≈ a is Some

Compare Some(…) to another Some(…):

• assert_some_eq!(a, b) ≈ (a ⇒ Some(a1) ⇒ a1) = (b ⇒ Some(b1) ⇒ b1)
• assert_some_ne!(a, b) ≈ (a ⇒ Some(a1) ⇒ a1) ≠ (b ⇒ Some(b1) ⇒ b1)

Compare Some(…) to an expression:

• assert_some_eq_x!(a, expr) ≈ (a ⇒ Some(a1) ⇒ a1) = expr
• assert_some_ne_x!(a, expr) ≈ (a ⇒ Some(a1) ⇒ a1) ≠ expr

Example

use assertables::*;

let a: Option<i8> = Option::Some(1);
assert_some!(a);
