A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the `String(describing:)`
initializer. This initializer works with any type, and uses the custom
`description` property for types that conform to
`CustomStringConvertible`:
struct Point: CustomStringConvertible {
let x: Int, y: Int
var description: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"
The conversion of `p` to a string in the assignment to `s` uses the
`Point` type's `description` property.

Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the `String(reflecting:)`
initializer. This initializer works with any type, and uses the custom
`debugDescription` property for types that conform to
`CustomDebugStringConvertible`:
struct Point: CustomDebugStringConvertible {
let x: Int, y: Int
var debugDescription: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(reflecting: p)
print(s)
// Prints "(21, 30)"
The conversion of `p` to a string in the assignment to `s` uses the

externalReference
TypeScript
get externalReference(): ComputeNodeGraph_Port_Options
Swift declaration
static let externalReference: ComputeNodeGraph.Port.Options
The port references a value outside of the graph, such as by filename
get · iOS 27.0+
compile
TypeScript
get compile(): ComputeNodeGraph_Port_Options
Swift declaration
static let compile: ComputeNodeGraph.Port.Options
Port affects compilation.
Changes to ``compile`` values require recompiling the pipeline

argument
TypeScript
get argument(): ComputeNodeGraph_Port_Options
Swift declaration
static let argument: ComputeNodeGraph.Port.Options
Port is an argument to a runtime function.
These correspond to a function parameter.

constant
TypeScript
get constant(): ComputeNodeGraph_Port_Options
Swift declaration
static let constant: ComputeNodeGraph.Port.Options
Port is constant and doesn't need to be changeable.
Parameters with ``constant`` that are available at compile time can aid in optimization.

optional
TypeScript
get optional(): ComputeNodeGraph_Port_Options
Swift declaration
static let optional: ComputeNodeGraph.Port.Options
Creates a new option set from the given raw value.
This initializer always succeeds, even if the value passed as `rawValue`
exceeds the static properties declared as part of the option set. This
example creates an instance of `ShippingOptions` with a raw value beyond
the highest element, with a bit mask that effectively contains all the
declared static members.
let extraOptions = ShippingOptions(rawValue: 255)
print(extraOptions.isStrictSuperset(of: .all))
// Prints "true"
- Parameter rawValue: The raw value of the option set to create. Each bit
of `rawValue` potentially represents an element of the option set,
though raw values may include bits that are not defined as distinct
values of the `OptionSet` type.

rawValue
TypeScript
getRawValue($self: ComputeNodeGraph_Port_Options): number
Swift declaration
let rawValue: UInt
The corresponding value of the raw type.
A new instance initialized with `rawValue` will be equivalent to this
instance. For example:
enum PaperSize: String {
case A4, A5, Letter, Legal
}
let selectedSize = PaperSize.Letter
print(selectedSize.rawValue)
// Prints "Letter"
print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!)
// Prints "true"
