Struct Node 

pub struct Node { /* private fields */ }

Proxy that represents a node that is connected to the server.

Implementations

impl Node

pub fn add_listener(&self, events: NodeEvents) -> HookId

Register for notifications of node events.

pub fn remove_listener(&self, hook_id: HookId)

Remove a set of event listeners.

pub fn subscribe_params(&self, ids: &[ParamType]) -> Result<()>

Register for notifications of the specified param types.

pub fn enum_params( &self, seq: u32, id: Option<ParamType>, start: u32, num: u32, filter: Option<ParamBuilder>, ) -> Result<()>

Enumerate params (via NodeEvents::param). Set id to None to query all param types.

pub fn set_param( &self, param_id: ParamType, object_type: ObjectType, flags: u32, builder: Box<dyn FnOnce(ObjectBuilder<'_>) -> ObjectBuilder<'_>>, ) -> Result<()>

Set a parameter on the node.

pub fn send_command( &self, builder: Box<dyn FnOnce(Builder<'_>) -> Builder<'_>>, ) -> Result<()>

Send a command to the node.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl HasProxy for Node

fn type_(&self) -> ObjectType

The interface type of the proxy object.

fn version(&self) -> u32

The interface version of the proxy object.

fn proxy(&self) -> Proxy<Self>

Get a Proxy<T> for this object.

impl Refcounted for Node

type WeakRef = WeakNode

The type of a weak reference to the object

fn upgrade(this: &Self::WeakRef) -> Option<Self>

Try to convert a weak reference to a strong reference. If the underlying object isstill alive, returns a Some continaing the value. If the underlying object’s strong reference count dropped to zero, and was thus freed, this returns None.

fn downgrade(&self) -> Self::WeakRef

Create a weak reference to the object. This reference does not impact the object’s lifecycle, and merely allows us the option to try to retrieve the object using Self::upgrade().

impl Send for Node

impl Sync for Node
