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

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 PacketPeerStream
[src]
pub fn new() -> Ref<PacketPeerStream, Unique>
[src]
Creates a new instance of this object.
This is a reference-counted type. The returned object is automatically managed
by Ref
.
pub fn input_buffer_max_size(&self) -> i64
[src]
pub fn output_buffer_max_size(&self) -> i64
[src]
pub fn stream_peer(&self) -> Option<Ref<StreamPeer, Shared>>
[src]
The wrapped [StreamPeer] object.
pub fn set_input_buffer_max_size(&self, max_size_bytes: i64)
[src]
pub fn set_output_buffer_max_size(&self, max_size_bytes: i64)
[src]
pub fn set_stream_peer(&self, peer: impl AsArg<StreamPeer>)
[src]
The wrapped [StreamPeer] object.
Methods from Deref<Target = PacketPeer>
pub fn get_available_packet_count(&self) -> i64
[src]
Returns the number of packets currently available in the ring-buffer.
pub fn encode_buffer_max_size(&self) -> i64
[src]
Maximum buffer size allowed when encoding [Variant]s. 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 [code]encode_buffer_max_size[/code], the method will error out with [constant ERR_OUT_OF_MEMORY].
pub fn get_packet(&self) -> TypedArray<u8>
[src]
Gets a raw packet.
pub fn get_packet_error(&self) -> Result<(), GodotError>
[src]
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
[src]
Gets a Variant. If [code]allow_objects[/code] (or [member allow_object_decoding]) is [code]true[/code], decoding objects is allowed.
[b]Warning:[/b] 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
[src]
[i]Deprecated.[/i] Use [code]get_var[/code] and [code]put_var[/code] parameters instead.
If [code]true[/code], the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var].
[b]Warning:[/b] 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: TypedArray<u8>) -> Result<(), GodotError>
[src]
Sends a raw packet.
pub fn put_var(
&self,
var: impl OwnedToVariant,
full_objects: bool
) -> Result<(), GodotError>
[src]
&self,
var: impl OwnedToVariant,
full_objects: bool
) -> Result<(), GodotError>
Sends a [Variant] as a packet. If [code]full_objects[/code] (or [member allow_object_decoding]) is [code]true[/code], encoding objects is allowed (and can potentially include code).
Default Arguments
full_objects
-false
pub fn set_allow_object_decoding(&self, enable: bool)
[src]
[i]Deprecated.[/i] Use [code]get_var[/code] and [code]put_var[/code] parameters instead.
If [code]true[/code], the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var].
[b]Warning:[/b] 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)
[src]
Maximum buffer size allowed when encoding [Variant]s. 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 [code]encode_buffer_max_size[/code], the method will error out with [constant ERR_OUT_OF_MEMORY].
