@Layout

Triggers a layout update whenever the wrapped variable's value changes.

@Layout var someVariable = false

// expands to

var someVariable = false {
    didSet {
        setNeedsLayout()
    }
}

@DistinctLayout

Triggers a layout update whenever the wrapped variable's value changes only if the new value is distinct from the old value.

@DistinctLayout var someVariable = false

// expands to

var someVariable = false {
    didSet {
        guard oldValue != someVariable else {
            return
        }

        setNeedsLayout()
    }
}

@ScrollLayout

Triggers a layout update whenever the wrapped variable's value changes.

@ScrollLayout var someVariable = false

// expands to

var someVariable = false {
    didSet {
        scrollNode.setNeedsLayout()
    }
}

@DistinctScrollLayout

Triggers a layout update whenever the wrapped variable's value changes only if the new value is distinct from the old value.

@DistinctScrollLayout var someVariable = false

// expands to

var someVariable = false {
    didSet {
        guard oldValue != someVariable else {
            return
        }

        scrollNode.setNeedsLayout()
    }
}

@DecodableDefaultCase

Adds an initializer that substitutes the first case as a default one if it fails to initialize with the given raw value.

@DecodableDefaultCase
enum SomeEnum: String, Codable {
    case undefined
    case first
}

// expands to

enum SomeEnum: String, Codable {
    case undefined
    case first
}

extension SomeEnum {
    public init(from decoder: Decoder) throws {
        self = try SomeEnum(rawValue: decoder.singleValueContainer().decode(RawValue.self)) ?? .undefined
    }
}
