appendInterpolation(_:format:align:privacy:attributes:)

Appends an interpolated numeric type using the specified attributes.

Declaration

mutating func appendInterpolation<T>(_ number: @autoclosure  @escaping () -> T, format: OSLogIntegerFormatting = .decimal, align: OSLogStringAlignment = .none, privacy: OSLogPrivacy = .auto, attributes: String) where T : FixedWidthInteger

Parameters

  • number:

    The interpolated numeric type, which the system automatically wraps in a closure. The type itself doesn’t appear in the log message. Instead, the system incorporates the type’s integer value.

  • format:

    The format to apply to the value when the system renders it in a log message. For more information, see Oslogintegerformatting. The default value is Decimal.

  • align:

    The alignment and minimum number of columns to use when the system renders the value in a log message. For more information, see Oslogstringalignment. The default value is None.

  • privacy:

    The privacy level of the value, which the system applies when it renders the value in a log message. For more information, see Oslogprivacy. The default value is Auto.

  • attributes:

    Additional information about the value. Tools that process log messages interpret these attributes, which you typically provide as key-value pairs. For example, Instruments processes any e_ngineering types_ you embed in this value. For more information, see Devcd5016d31.
