Struct PeerConfigBuilder 

pub struct PeerConfigBuilder { /* private fields */ }

Builds and represents a single peer in a WireGuard interface configuration.

Note that if a peer with that public key already exists on the interface, the settings specified here will be applied on top of the existing settings, similarly to interface-wide settings.

If this is not what you want, use DeviceUpdate::replace_peers() to replace all peer settings on the interface, or use DeviceUpdate::remove_peer_by_key() first to remove the peer from the interface and then apply a second configuration to re-add it.

Example

let peer_keypair = KeyPair::generate();

// create a new peer and allow it to connect from 192.168.1.2
let peer = PeerConfigBuilder::new(&peer_keypair.public)
    .replace_allowed_ips()
    .add_allowed_ip("192.168.1.2".parse()?, 32);

// update our existing configuration with the new peer
DeviceUpdate::new().add_peer(peer).apply(&"wg-example".parse().unwrap(), Backend::Userspace);

println!("Send these keys to your peer: {:#?}", peer_keypair);

Implementations

impl PeerConfigBuilder

pub fn new(public_key: &Key) -> Self

Creates a new PeerConfigBuilder that does nothing when applied.

pub fn into_peer_config(self) -> PeerConfig

pub fn public_key(&self) -> &Key

The public key used in this builder.

pub fn from_peer_config(config: PeerConfig) -> Self

Creates a PeerConfigBuilder from a PeerConfig.

This is mostly a convenience method for cases when you want to copy some or most of the existing peer configuration to a new configuration.

This returns a PeerConfigBuilder, so you can still call any methods you need to override the imported settings.

pub fn set_preshared_key(self, key: Key) -> Self

Specifies a preshared key to be set for this peer.

pub fn unset_preshared_key(self) -> Self

Specifies that this peer’s preshared key should be unset.

pub fn set_endpoint(self, address: SocketAddr) -> Self

Specifies an exact endpoint that this peer should be allowed to connect from.

pub fn set_persistent_keepalive_interval(self, interval: u16) -> Self

Specifies the interval between keepalive packets to be sent to this peer.

pub fn unset_persistent_keepalive(self) -> Self

Specifies that this peer does not require keepalive packets.

pub fn add_allowed_ip(self, address: IpAddr, cidr: u8) -> Self

Specifies an IP address this peer will be allowed to connect from/to.

See AllowedIp for details. This method can be called more than once, and all IP addresses will be added to the configuration.

pub fn add_allowed_ips(self, ips: &[AllowedIp]) -> Self

Specifies multiple IP addresses this peer will be allowed to connect from/to.

See AllowedIp for details. This method can be called more than once, and all IP addresses will be added to the configuration.

pub fn allow_all_ips(self) -> Self

Specifies this peer should be allowed to connect to all IP addresses.

This is a convenience method for cases when you want to connect to a server that all traffic should be routed through.

pub fn replace_allowed_ips(self) -> Self

Specifies that the allowed IP addresses in this configuration should replace the existing configuration of the interface, not be appended to it.

pub fn remove(self) -> Self

Mark peer for removal from interface.

Trait Implementations

impl Clone for PeerConfigBuilder

fn clone(&self) -> PeerConfigBuilder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PeerConfigBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PeerConfigBuilder

impl PartialEq for PeerConfigBuilder

fn eq(&self, other: &PeerConfigBuilder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
