System

import NIOCore

The core abstractions that make up SwiftNIO.

struct NIONetworkDevice

A representation of a single network device on a system.

final class NIONetworkInterface

A representation of a single network interface on a system.

enum SocketAddress

Represent a socket address to which we may want to connect or bind.

enum NIOBSDSocket

struct NIOIPProtocol

In the Internet Protocol version 4 (IPv4) [RFC791] there is a field called “Protocol” to identify the next level protocol. This is an 8 bit field. In Internet Protocol version 6 (IPv6) [RFC8200], this field is called the “Next Header” field.

static var coreCount: Int { get }

A utility function that returns an estimate of the number of logical cores on the system available for use.

static let supportsUDPReceiveOffload: Bool

Returns true if the platform supports UDP_GRO.

static let supportsUDPSegmentationOffload: Bool

Returns true if the platform supports UDP_SEGMENT (GSO).

static var udpMaxSegments: Int? { get }

Returns the UDP maximum segment count if the platform supports and defines it.

static func enumerateDevices() throws -> [NIONetworkDevice]

A utility function that enumerates the available network devices on this machine.

static func enumerateInterfaces() throws -> [NIONetworkInterface]

A utility function that enumerates the available network interfaces on this machine.
