rawValue

import NIOCore

The core abstractions that make up SwiftNIO.

struct Option

Defines configuration option names.

enum NIOBSDSocket

typealias RawValue = CInt

init(rawValue: RawValue)

static let ip_add_membership: NIOBSDSocket.Option

Add a multicast group membership.

static let ip_drop_membership: NIOBSDSocket.Option

Drop a multicast group membership.

static let ip_hdrincl: NIOBSDSocket.Option

The IPv4 layer generates an IP header when sending a packet unless the ip_hdrincl socket option is enabled on the socket. When it is enabled, the packet must contain an IP header. For receiving, the IP header is always included in the packet.

static let ip_multicast_if: NIOBSDSocket.Option

Set the interface for outgoing multicast packets.

static let ip_multicast_loop: NIOBSDSocket.Option

Control multicast loopback.

static let ip_multicast_ttl: NIOBSDSocket.Option

Control multicast time-to-live.

static let ipv6_join_group: NIOBSDSocket.Option

Add an IPv6 group membership.

static let ipv6_leave_group: NIOBSDSocket.Option

Drop an IPv6 group membership.

static let ipv6_multicast_hops: NIOBSDSocket.Option

Specify the maximum number of router hops for an IPv6 packet.

static let ipv6_multicast_if: NIOBSDSocket.Option

Set the interface for outgoing multicast packets.

static let ipv6_multicast_loop: NIOBSDSocket.Option

Control multicast loopback.

static let ipv6_v6only: NIOBSDSocket.Option

Indicates if a socket created for the AF_INET6 address family is restricted to IPv6 only.

static let mptcp_info: NIOBSDSocket.Option

Get info about an MPTCP connection

static let so_broadcast: NIOBSDSocket.Option

Allows the socket to send broadcast messages.

static let so_error: NIOBSDSocket.Option

Get the error status and clear.

static let so_keepalive: NIOBSDSocket.Option

Use keep-alives.

static let so_linger: NIOBSDSocket.Option

Linger on close if unsent data is present.

static let so_rcvbuf: NIOBSDSocket.Option

Specifies the total per-socket buffer space reserved for receives.

static let so_rcvtimeo: NIOBSDSocket.Option

Specifies the receive timeout.

static let so_reuseaddr: NIOBSDSocket.Option

Allows the socket to be bound to an address that is already in use.

static let so_sndbuf: NIOBSDSocket.Option

Specifies the total per-socket buffer space reserved for sends.

static let so_timestamp: NIOBSDSocket.Option

Indicate when to generate timestamps.

static let tcp_info: NIOBSDSocket.Option

Get information about the TCP connection.

static let tcp_nodelay: NIOBSDSocket.Option

Disables the Nagle algorithm for send coalescing.

static let udp_gro: NIOBSDSocket.Option

Use UDP generic receive offload (GRO). Only available on Linux.

static let udp_segment: NIOBSDSocket.Option

Use UDP segmentation offload (UDP_SEGMENT, or ‘GSO’). Only available on Linux.
