ChildDirective

A property wrapper that represents a child directive.

@propertyWrapper struct ChildDirective<Value>

Discussion

This property wrapper is used internally in Swift-DocC when declaring directives that support specific child directives.

class Row: Semantic, AutomaticDirectiveConvertible {
    let originalMarkup: BlockDirective

    @ChildDirective
    private(set) var columns: [Column]

    static var keyPaths: [String : AnyKeyPath] = [
        "columns" : \Row._columns,
    ]

    init(originalMarkup: BlockDirective) {
        self.originalMarkup = originalMarkup
    }
}

Warning
This property wrapper is exposed as public API of SwiftDocC so that clients have access to its projected value, but it is unsupported to attach this property wrapper to new declarations outside of SwiftDocC.
