Why struct marked with @resultBuilder replaced by enum

[Mickael-tinytap]

Hi,

I noticed that a struct maked with @resultBuilder he is replaced by an enum

From:

    @resultBuilder
    struct TinyAlertBuilder {
        static func buildBlock(_ components: TinyAlertAction...) -> [TinyAlertAction] {
            return components
        }
    }

To:

    @resultBuilder
    enum TinyAlertBuilder {
        static func buildBlock(_ components: TinyAlertAction...) -> [TinyAlertAction] {
            return components
        }
    }

What is the reason? and what is the name of the parameter that responsable to this feature?

This is the enumNamespaces rule: https://github.com/nicklockwood/SwiftFormat/blob/master/Rules.md#enumNamespaces

I didn't anticipate the rule being applied to resultBuilders, but it seems not to cause any build errors. Happy to consider excluding them if you think there's a good reason to do so?

I don't know, I don't think that there is any different in this case between struct and enum both are values type. But it's can be good to add new parameter for this case maybe? Because struct is most used way to write @resultBuilder
