appendInterpolation(_:align:privacy:)
Appends an interpolated textual representation of a type.
Declaration
mutating func appendInterpolation<T>(_ value: @autoclosure @escaping () -> T, align: OSLogStringAlignment = .none, privacy: OSLogPrivacy = .auto) where T : CustomStringConvertibleParameters
- value:
An item that conforms to the Customstringconvertible protocol.
- align:
The alignment to apply to the string. Use this parameter to specify the width of the column containing the data, and the alignment of the data within that column. If you don’t specify this parameter, the system doesn’t align the value.
- privacy:
The privacy level of the information. If you don’t specify this parameter, the system uses the default rules to determine whether to show the information.
Discussion
Don’t call this function directly. The system calls it automatically when interpolating values of this type. When specifying the value in your string, you may include any of the indicated parameters to change the default presentation of that value.
