Struct gdnative_bindings::WebSocketServer

pub struct WebSocketServer { /* fields omitted */ }

core class WebSocketServer inherits WebSocketMultiplayerPeer (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

WebSocketServer inherits methods from:

• WebSocketMultiplayerPeer
• NetworkedMultiplayerPeer
• PacketPeer
• 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 WebSocketServer

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

    output_buffer_size_kb: i64,
    output_max_packets: i64
) -> GodotResult

pub const CONNECTION_CONNECTED: i64

pub const CONNECTION_CONNECTING: i64

pub const CONNECTION_DISCONNECTED: i64

pub const TARGET_PEER_BROADCAST: i64

pub const TARGET_PEER_SERVER: i64

pub const TRANSFER_MODE_RELIABLE: i64

pub const TRANSFER_MODE_UNRELIABLE: i64

pub const TRANSFER_MODE_UNRELIABLE_ORDERED: i64

pub fn get_connection_status(&self) -> ConnectionStatus

Returns the current state of the connection. See [enum ConnectionStatus].

pub fn get_packet_peer(&self) -> i64

Returns the ID of the NetworkedMultiplayerPeer who sent the most recent packet.

pub fn transfer_mode(&self) -> TransferMode

The manner in which to send packets to the target_peer. See [enum TransferMode].

pub fn get_unique_id(&self) -> i64

Returns the ID of this NetworkedMultiplayerPeer.

pub fn is_refusing_new_connections(&self) -> bool

If true, this NetworkedMultiplayerPeer refuses new connections.

pub fn poll(&self)

Waits up to 1 second to receive a new network event.

pub fn set_refuse_new_connections(&self, enable: bool)

If true, this NetworkedMultiplayerPeer refuses new connections.

pub fn set_target_peer(&self, id: i64)

Sets the peer to which packets will be sent. The id can be one of: [constant TARGET_PEER_BROADCAST] to send to all connected peers, [constant TARGET_PEER_SERVER] to send to the peer acting as server, a valid peer ID to send to that specific peer, a negative peer ID to send to all peers except that one. By default, the target peer is [constant TARGET_PEER_BROADCAST].

pub fn set_transfer_mode(&self, mode: i64)

The manner in which to send packets to the target_peer. See [enum TransferMode].

Methods from Deref<Target = PacketPeer>

pub fn get_available_packet_count(&self) -> i64

Returns the number of packets currently available in the ring-buffer.

pub fn encode_buffer_max_size(&self) -> i64

Maximum buffer size allowed when encoding Variants. Raise this value to support heavier memory allocations. The [method put_var] method allocates memory on the stack, and the buffer used will grow automatically to the closest power of two to match the size of the Variant. If the Variant is bigger than encode_buffer_max_size, the method will error out with [constant ERR_OUT_OF_MEMORY].

pub fn get_packet(&self) -> ByteArray

Gets a raw packet.

pub fn get_packet_error(&self) -> GodotResult

Returns the error state of the last packet received (via [method get_packet] and [method get_var]).

pub fn get_var(&self, allow_objects: bool) -> Variant

Gets a Variant. If allow_objects (or [member allow_object_decoding]) is true, decoding objects is allowed. Warning: Deserialized objects can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats such as remote code execution.

Default Arguments

• allow_objects - false

pub fn is_object_decoding_allowed(&self) -> bool

[i]Deprecated.[/i] Use get_var and put_var parameters instead. If true, the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var]. Warning: Deserialized objects can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats such as remote code execution.

pub fn put_packet(&self, buffer: ByteArray) -> GodotResult

Sends a raw packet.

pub fn put_var(
    &self,
    var: impl OwnedToVariant,
    full_objects: bool
) -> GodotResult

Sends a Variant as a packet. If full_objects (or [member allow_object_decoding]) is true, encoding objects is allowed (and can potentially include code).

Default Arguments

• full_objects - false

pub fn set_allow_object_decoding(&self, enable: bool)

[i]Deprecated.[/i] Use get_var and put_var parameters instead. If true, the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var]. Warning: Deserialized objects can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats such as remote code execution.

pub fn set_encode_buffer_max_size(&self, max_size: i64)

Maximum buffer size allowed when encoding Variants. Raise this value to support heavier memory allocations. The [method put_var] method allocates memory on the stack, and the buffer used will grow automatically to the closest power of two to match the size of the Variant. If the Variant is bigger than encode_buffer_max_size, the method will error out with [constant ERR_OUT_OF_MEMORY].

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.

Methods from Deref<Target = Object>

pub const CONNECT_DEFERRED: i64

pub const CONNECT_ONESHOT: i64

pub const CONNECT_PERSIST: i64

pub const CONNECT_REFERENCE_COUNTED: i64

pub const NOTIFICATION_POSTINITIALIZE: i64

pub const NOTIFICATION_PREDELETE: i64

pub fn add_user_signal(
    &self,
    signal: impl Into<GodotString>,
    arguments: VariantArray
)

Adds a user-defined signal. Arguments are optional, but can be added as an [Array] of dictionaries, each containing name: String and type: int (see [enum Variant.Type]) entries.

Default Arguments

• arguments - [ ]

pub unsafe fn call(
    &self,
    method: impl Into<GodotString>,
    varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust's static type checks (aliasing, thread boundaries, calls to free(), ...).

pub unsafe fn call_deferred(
    &self,
    method: impl Into<GodotString>,
    varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call_deferred("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust's static type checks (aliasing, thread boundaries, calls to free(), ...).

pub unsafe fn callv(
    &self,
    method: impl Into<GodotString>,
    arg_array: VariantArray
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. Contrarily to [method call], this method does not support a variable number of arguments but expects all parameters to be via a single [Array].

callv("set", [ "position", Vector2(42.0, 0.0) ])

Safety

This function bypasses Rust's static type checks (aliasing, thread boundaries, calls to free(), ...).

pub fn can_translate_messages(&self) -> bool

Returns true if the object can translate strings. See [method set_message_translation] and [method tr].

pub fn connect(
    &self,
    signal: impl Into<GodotString>,
    target: impl AsArg<Object>,
    method: impl Into<GodotString>,
    binds: VariantArray,
    flags: i64
) -> GodotResult

Sample code is GDScript unless otherwise noted.

Connects a signal to a method on a target object. Pass optional binds to the call as an [Array] of parameters. These parameters will be passed to the method after any parameter used in the call to [method emit_signal]. Use flags to set deferred or one-shot connections. See [enum ConnectFlags] constants. A signal can only be connected once to a method. It will throw an error if already connected, unless the signal was connected with [constant CONNECT_REFERENCE_COUNTED]. To avoid this, first, use [method is_connected] to check for existing connections. If the target is destroyed in the game's lifecycle, the connection will be lost. Examples:

connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal

An example of the relationship between binds passed to [method connect] and parameters used when calling [method emit_signal]:

connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
    print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])

Default Arguments

• binds - [ ]
• flags - 0

pub fn disconnect(
    &self,
    signal: impl Into<GodotString>,
    target: impl AsArg<Object>,
    method: impl Into<GodotString>
)

Disconnects a signal from a method on the given target. If you try to disconnect a connection that does not exist, the method will throw an error. Use [method is_connected] to ensure that the connection exists.

pub fn emit_signal(
    &self,
    signal: impl Into<GodotString>,
    varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Emits the given signal. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

emit_signal("hit", weapon_type, damage)
emit_signal("game_over")

pub fn get(&self, property: impl Into<GodotString>) -> Variant

Returns the Variant value of the given property. If the property doesn't exist, this will return null. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn get_class(&self) -> GodotString

Returns the object's class as a String.

pub fn get_incoming_connections(&self) -> VariantArray

Returns an [Array] of dictionaries with information about signals that are connected to the object. Each Dictionary contains three String entries:

• source is a reference to the signal emitter.
• signal_name is the name of the connected signal.
• method_name is the name of the method to which the signal is connected.

pub fn get_indexed(&self, property: impl Into<NodePath>) -> Variant

Gets the object's property indexed by the given NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Examples: "position:x" or "material:next_pass:blend_mode".

pub fn get_instance_id(&self) -> i64

Returns the object's unique instance ID. This ID can be saved in EncodedObjectAsID, and can be used to retrieve the object instance with [method @GDScript.instance_from_id].

pub fn get_meta(&self, name: impl Into<GodotString>) -> Variant

Returns the object's metadata entry for the given name.

pub fn get_meta_list(&self) -> StringArray

Returns the object's metadata as a [PoolStringArray].

pub fn get_method_list(&self) -> VariantArray

Returns the object's methods and their signatures as an [Array].

pub fn get_property_list(&self) -> VariantArray

Returns the object's property list as an [Array] of dictionaries. Each property's Dictionary contain at least name: String and type: int (see [enum Variant.Type]) entries. Optionally, it can also include hint: int (see [enum PropertyHint]), hint_string: String, and usage: int (see [enum PropertyUsageFlags]).

pub fn get_script(&self) -> Option<Ref<Reference, Shared>>

Returns the object's Script instance, or null if none is assigned.

pub fn get_signal_connection_list(
    &self,
    signal: impl Into<GodotString>
) -> VariantArray

Returns an [Array] of connections for the given signal.

pub fn get_signal_list(&self) -> VariantArray

Returns the list of signals as an [Array] of dictionaries.

pub fn has_meta(&self, name: impl Into<GodotString>) -> bool

Returns true if a metadata entry is found with the given name.

pub fn has_method(&self, method: impl Into<GodotString>) -> bool

Returns true if the object contains the given method.

pub fn has_signal(&self, signal: impl Into<GodotString>) -> bool

Returns true if the given signal exists.

pub fn has_user_signal(&self, signal: impl Into<GodotString>) -> bool

Returns true if the given user-defined signal exists. Only signals added using [method add_user_signal] are taken into account.

pub fn is_blocking_signals(&self) -> bool

Returns true if signal emission blocking is enabled.

pub fn is_class(&self, class: impl Into<GodotString>) -> bool

Returns true if the object inherits from the given class.

pub fn is_connected(
    &self,
    signal: impl Into<GodotString>,
    target: impl AsArg<Object>,
    method: impl Into<GodotString>
) -> bool

Returns true if a connection exists for a given signal, target, and method.

pub fn is_queued_for_deletion(&self) -> bool

Returns true if the [method Node.queue_free] method was called for the object.

pub fn notification(&self, what: i64, reversed: bool)

Send a given notification to the object, which will also trigger a call to the [method _notification] method of all classes that the object inherits from. If reversed is true, [method _notification] is called first on the object's own class, and then up to its successive parent classes. If reversed is false, [method _notification] is called first on the highest ancestor (Object itself), and then down to its successive inheriting classes.

Default Arguments

• reversed - false

pub fn property_list_changed_notify(&self)

Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.

pub fn remove_meta(&self, name: impl Into<GodotString>)

Removes a given entry from the object's metadata. See also [method set_meta].

pub fn set(&self, property: impl Into<GodotString>, value: impl OwnedToVariant)

Assigns a new value to the given property. If the property does not exist, nothing will happen. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn set_block_signals(&self, enable: bool)

If set to true, signal emission is blocked.

pub fn set_deferred(
    &self,
    property: impl Into<GodotString>,
    value: impl OwnedToVariant
)

Assigns a new value to the given property, after the current frame's physics step. This is equivalent to calling [method set] via [method call_deferred], i.e. call_deferred("set", property, value). Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn set_indexed(
    &self,
    property: impl Into<NodePath>,
    value: impl OwnedToVariant
)

Sample code is GDScript unless otherwise noted.

Assigns a new value to the property identified by the NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Example:

set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)

pub fn set_message_translation(&self, enable: bool)

Defines whether the object can translate strings (with calls to [method tr]). Enabled by default.

pub fn set_meta(&self, name: impl Into<GodotString>, value: impl OwnedToVariant)

Adds, changes or removes a given entry in the object's metadata. Metadata are serialized and can take any Variant value. To remove a given entry from the object's metadata, use [method remove_meta]. Metadata is also removed if its value is set to null. This means you can also use set_meta("name", null) to remove metadata for "name".

pub fn set_script(&self, script: impl AsArg<Reference>)

Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality. If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script's [method _init] method will be called.

pub fn to_string(&self) -> GodotString

Returns a String representing the object. If not overridden, defaults to "[ClassName:RID]". Override the method [method _to_string] to customize the String representation.

pub fn tr(&self, message: impl Into<GodotString>) -> GodotString

Translates a message using translation catalogs configured in the Project Settings. Only works if message translation is enabled (which it is by default), otherwise it returns the message unchanged. See [method set_message_translation].
