### Create and Register a Local Listener

Source: https://pipewire.pages.freedesktop.org/pipewire-rs/pipewire/registry/struct.ListenerLocalBuilder.html

Use `Registry::add_listener_local` to create a builder, configure callbacks, and then call `register` to get a `registry::Listener`. This example shows how to set up callbacks for both global object addition and removal.

```rust
let registry_listener = registry.add_listener_local()
    .global(|global| println!("New global: {global:?}"))
    .global_remove(|id| println!("Global with id {id} was removed"))
    .register();
```

--------------------------------

### Example: Creating a new link

Source: https://pipewire.pages.freedesktop.org/pipewire-rs/pipewire/core/struct.Core.html

Demonstrates how to create a new link object on the PipeWire server using the `create_object` method. This example uses turbofish syntax to specify the desired object type.

```rust
use pipewire as pw;

pw::init();

let mainloop = pw::MainLoop::new().expect("Failed to create Pipewire Mainloop");
let context = pw::Context::new(&mainloop).expect("Failed to create Pipewire Context");
let core = context
    .connect(None)
    .expect("Failed to connect to Pipewire Core");

// This call uses turbofish syntax to specify that we want a link.
let link = core.create_object::<pw::link::Link>(
    // The actual name for a link factory might be different for your system,
    // you should probably obtain a factory from the registry.
    "link-factory",
    &pw::properties! {
        "link.output.port" => "1",
        "link.input.port" => "2",
        "link.output.node" => "3",
        "link.input.node" => "4"
    },
)
.expect("Failed to create object");
```

### Create and Register Node Listener

Source: https://pipewire.pages.freedesktop.org/pipewire-rs/pipewire/node/struct.NodeListenerLocalBuilder.html

Use `Node::add_listener_local` to create a builder and register callbacks for node events. Call `register` to finalize the listener.

```rust
let node_listener = node.add_listener_local()
    .info(|info| println!("New node info: {info:?}"))
    .param(|seq, param_type, index, next, param| {
        println!("New node param: seq {seq}, param type {param_type:?}, index {index}, next {next}, param {:?}",
            param.map(Pod::as_bytes));
    })
    .register();
```
