error[E0369]: binary operation `==` cannot be applied to type `fn() -> i32 {a}` | ||

LL | assert_eq!(a, 0); | ||

| fn() -> i32 {a} | ||
| {integer} | ||
| help: you might have forgotten to call this function: `*left_val()` | ||

error[E0277]: `fn() -> i32 {a}` doesn't implement `std::fmt::Debug` | ||

LL | fn a() -> i32 { | ||

... | ||
LL | assert_eq!(a, 0); | ||
| ^^^^^^^^^^^^^^^^^ `fn() -> i32 {a}` cannot be formatted using `{:?}` because it doesn't implement `std::fmt::Debug` | ||
| | ||
= help: the trait `std::fmt::Debug` is not implemented for `fn() -> i32 {a}` | ||
= help: use parentheses to call the function: `a()` | ||
= note: required because of the requirements on the impl of `std::fmt::Debug` for `&fn() -> i32 {a}` | ||
= note: required by `std::fmt::Debug::fmt` | ||
