Struct gdnative_bindings_lily::UDPServer

pub struct UDPServer { /* fields omitted */ }

core class UDPServer inherits Reference (reference counted).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

UDPServer inherits methods from:

• Reference
• Object

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl UDPServer

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

pub fn max_pending_connections(&self) -> i64

Define the maximum number of pending connections, during [method poll], any new pending connection exceeding that value will be automatically dropped. Setting this value to 0 effectively prevents any new pending connection to be accepted (e.g. when all your players have connected).

pub fn is_connection_available(&self) -> bool

Returns true if a packet with a new address/port combination was received on the socket.

pub fn is_listening(&self) -> bool

Returns true if the socket is open and listening on a port.

pub fn listen(
    &self,
    port: i64,
    bind_address: impl Into<GodotString>
) -> GodotResult

Starts the server by opening a UDP socket listening on the given port. You can optionally specify a bind_address to only listen for packets sent to that address. See also [method PacketPeerUDP.listen].

Default Arguments

• bind_address - "*"

pub fn poll(&self) -> GodotResult

Call this method at regular intervals (e.g. inside [method Node._process]) to process new packets. And packet from known address/port pair will be delivered to the appropriate PacketPeerUDP, any packet received from an unknown address/port pair will be added as a pending connection (see [method is_connection_available], [method take_connection]). The maximum number of pending connection is defined via [member max_pending_connections].

pub fn set_max_pending_connections(&self, max_pending_connections: i64)

Define the maximum number of pending connections, during [method poll], any new pending connection exceeding that value will be automatically dropped. Setting this value to 0 effectively prevents any new pending connection to be accepted (e.g. when all your players have connected).

pub fn stop(&self)

Stops the server, closing the UDP socket if open. Will close all connected PacketPeerUDP accepted via [method take_connection] (remote peers will not be notified).

pub fn take_connection(&self) -> Option<Ref<PacketPeerUDP, Shared>>

Returns the first pending connection (connected to the appropriate address/port). Will return null if no new connection is available. See also [method is_connection_available], [method PacketPeerUDP.connect_to_host].

Methods from Deref<Target = Reference>

pub fn init_ref(&self) -> bool

Initializes the internal reference counter. Use this only if you really know what you are doing. Returns whether the initialization was successful.

Trait Implementations

impl Debug for UDPServer

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

Formats the value using the given formatter.

impl Deref for UDPServer

type Target = Reference

The resulting type after dereferencing.

fn deref(&self) -> &Reference

Dereferences the value.

impl DerefMut for UDPServer

fn deref_mut(&mut self) -> &mut Reference

Mutably dereferences the value.

impl GodotObject for UDPServer

type RefKind = RefCounted

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>, 

Performs a dynamic reference downcast to target type.

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject, 

Performs a static reference upcast to a supertype that is guaranteed to be valid.

unsafe fn assume_shared(&self) -> Ref<Self, Shared>

Creates a persistent reference to the same Godot object with shared thread access.

unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where
    Self: GodotObject<RefKind = RefCounted>, 

Creates a persistent reference to the same Godot object with thread-local thread access.

unsafe fn assume_unique(&self) -> Ref<Self, Unique>

Creates a persistent reference to the same Godot object with unique access.

unsafe fn try_from_instance_id<'a>(id: i64) -> Option<TRef<'a, Self, Shared>>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive. See also TRef::try_from_instance_id.

unsafe fn from_instance_id<'a>(id: i64) -> TRef<'a, Self, Shared>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive, and panics otherwise. This does NOT guarantee that the resulting reference is safe to use.
