Lexeme.swift:28This declaration is gated by at least one @_spi attribute.
struct FlagsThis declaration is gated by at least one @_spi attribute.
struct Flagsimport SwiftParserA parser for the Swift programming language.
struct LexemeA trivia-delimited region of source text.
enum LexerA lexical analyzer for the Swift programming language.

protocol EquatableA type that can be compared for value equality.
protocol ExpressibleByArrayLiteralA type that can be initialized using an array literal.
protocol OptionSet : RawRepresentable, SetAlgebraA type that presents a mathematical set interface to a bit set.
protocol RawRepresentable<RawValue>A type that can be converted to and from an associated raw value.
protocol SendableA thread-safe type whose values can be shared across arbitrary concurrent contexts without introducing a risk of data races. Values of the type may have no shared mutable state, or they may protect that state with a lock or by forcing it to only be accessed from a specific actor.
protocol SetAlgebra<Element> : Equatable, ExpressibleByArrayLiteralA type that provides mathematical set operations.
init(rawValue: UInt8) static let isAtStartOfLine: Lexer.Lexeme.Flagsvar debugDescription: String { get }var rawValue: UInt8init() Creates an empty option set.
init<S>(_ sequence: S) where S : Sequence, Self.Element == S.Element Creates a new set from a finite sequence of items.
init(arrayLiteral: Self.Element...) Creates a set containing the elements of the given array literal.
var isEmpty: Bool { get }A Boolean value that indicates whether the set has no elements.
static func != (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether two values are not equal.
func contains(_ member: Self) -> Bool Returns a Boolean value that indicates whether a given element is a member of the option set.
mutating func formIntersection(_ other: Self) Removes all elements of this option set that are not also present in the given set.
mutating func formSymmetricDifference(_ other: Self) Replaces this set with a new set containing all elements contained in either this set or the given set, but not in both.
mutating func formUnion(_ other: Self) Inserts the elements of another set into this option set.
@discardableResult mutating func insert(_ newMember: Self.Element) -> (inserted: Bool, memberAfterInsert: Self.Element) Adds the given element to the option set if it is not already a member.
func intersection(_ other: Self) -> Self Returns a new option set with only the elements contained in both this set and the given set.
func isDisjoint(with other: Self) -> Bool Returns a Boolean value that indicates whether the set has no members in common with the given set.
func isStrictSubset(of other: Self) -> Bool Returns a Boolean value that indicates whether this set is a strict subset of the given set.
func isStrictSuperset(of other: Self) -> Bool Returns a Boolean value that indicates whether this set is a strict superset of the given set.
func isSubset(of other: Self) -> Bool Returns a Boolean value that indicates whether the set is a subset of another set.
func isSuperset(of other: Self) -> Bool Returns a Boolean value that indicates whether the set is a superset of the given set.
@discardableResult mutating func remove(_ member: Self.Element) -> Self.Element? Removes the given element and all elements subsumed by it.
mutating func subtract(_ other: Self) Removes the elements of the given set from this set.
func subtracting(_ other: Self) -> Self Returns a new set containing the elements of this set that do not occur in the given set.
func symmetricDifference(_ other: Self) -> Self Returns a new option set with the elements contained in this set or in the given set, but not in both.
func union(_ other: Self) -> Self Returns a new option set of the elements contained in this set, in the given set, or in both.
@discardableResult mutating func update(with newMember: Self.Element) -> Self.Element? Inserts the given element into the set.
