  • It may be possible to use the Any trait to “launder” the value by first casting it to &Any and then downcasting it to the generic type.

    let any_value = match tmp_value {
        serde_json::Value::Number(x) => x as &Any,
        // ...
    };
    
    let maybe_value = any_value.downcast_ref::< T >();
    

    I haven’t tested it, so I may have missed something.

    Edit: to be clear, this will not actually let you return multiple types, but let the caller decide which type to expect. I assumed this was your goal.




  • Also the Swedish classic “glida in på en räkmacka” ((to) slide in on a shrimp sandwich), which basically means to end up somewhere (location, career, situation) without any difficulties. The shrimp sandwich symbolizes a life without difficulties or in some luxury.

    Then there’s also “halka in på ett bananskal” ((to) slip in on a banana peel), which is similar to the above, but not always favorable and you don’t have any plan or preparation. You just winged it or it just happened by accident.
