✅ Disjunctive patterns negation

Hey there.

I was wondering why my disjunctive is not working as intended:

authUser.Level
> Internal
authUser.Level is UserLevel.Administrator
> false
authUser.Level is UserLevel.Internal
> true
authUser.Level is not UserLevel.Administrator or UserLevel.Internal
> true

authUser.Level
> Internal
authUser.Level is UserLevel.Administrator
> false
authUser.Level is UserLevel.Internal
> true
authUser.Level is not UserLevel.Administrator or UserLevel.Internal
> true

authUser.Level
> Internal
authUser.Level is UserLevel.Administrator
> false
authUser.Level is UserLevel.Internal
> true
authUser.Level is not UserLevel.Administrator or UserLevel.Internal
> true

authUser.Level
> Internal
authUser.Level is UserLevel.Administrator
> false
authUser.Level is UserLevel.Internal
> true
authUser.Level is not UserLevel.Administrator or UserLevel.Internal
> true

The last expression result doesn't make sense for me, because I'm checking if

authUser.Level

authUser.Level

is not

Administrator

Administrator

Internal

Internal

, and it actually is

Internal

Internal

as shown in the first expression, so the result should be

false

false

.

What i'm doing wrong?

probably need to use parenthesis around your

or

or

for the

not

not

to function as expected

but why putting an parenthesis on it? does

(UserLevel.Administrator or UserLevel.Internal)

(UserLevel.Administrator or UserLevel.Internal)

produces an enum with equality to both values or am i missing something else?

Because your example shows that it is clearly matching against

not UserLevel.Administrator

not UserLevel.Administrator

and

UserLevel.Internal

UserLevel.Internal

so the ideal, without the parenthesis, would be

authUser.Level is not UserLevel.Internal and not UserLevel.Administrator

authUser.Level is not UserLevel.Internal and not UserLevel.Administrator

Keswiik•4/15/24, 6:24 PM

correct

CEO da CloudFlareOP•4/15/24, 6:25 PM

pretty confusing

but that's it, thank you
