Struct ChannelOwnerImpl 

pub struct ChannelOwnerImpl { /* private fields */ }

Base implementation of ChannelOwner that can be embedded in protocol objects.

This struct provides the common functionality for all ChannelOwner implementations. Protocol objects (Browser, Page, etc.) should contain this as a field and delegate trait methods to it.

Example

use playwright_core::channel_owner::{ChannelOwner, ChannelOwnerImpl, ParentOrConnection, DisposeReason};
use playwright_core::channel::Channel;
use playwright_core::connection::ConnectionLike;
use std::sync::Arc;
use std::any::Any;
use serde_json::Value;

pub struct Browser {
    base: ChannelOwnerImpl,
    // ... browser-specific fields
}

impl Browser {
    pub fn new(
        parent: Arc<dyn ChannelOwner>,
        type_name: String,
        guid: Arc<str>,
        initializer: Value,
    ) -> Self {
        let base = ChannelOwnerImpl::new(
            ParentOrConnection::Parent(parent),
            type_name,
            guid,
            initializer,
        );
        Self { base }
    }
}

impl ChannelOwner for Browser {
    fn guid(&self) -> &str { self.base.guid() }
    fn type_name(&self) -> &str { self.base.type_name() }
    fn parent(&self) -> Option<Arc<dyn ChannelOwner>> { self.base.parent() }
    fn connection(&self) -> Arc<dyn ConnectionLike> { self.base.connection() }
    fn initializer(&self) -> &Value { self.base.initializer() }
    fn channel(&self) -> &Channel { self.base.channel() }
    fn dispose(&self, reason: DisposeReason) { self.base.dispose(reason) }
    fn adopt(&self, child: Arc<dyn ChannelOwner>) { self.base.adopt(child) }
    fn add_child(&self, guid: Arc<str>, child: Arc<dyn ChannelOwner>) {
        self.base.add_child(guid, child)
    }
    fn remove_child(&self, guid: &str) { self.base.remove_child(guid) }
    fn on_event(&self, method: &str, params: Value) { self.base.on_event(method, params) }
    fn was_collected(&self) -> bool { self.base.was_collected() }
    fn as_any(&self) -> &dyn Any { self }
}

Implementations

impl ChannelOwnerImpl

pub fn new( parent: ParentOrConnection, type_name: String, guid: Arc<str>, initializer: Value, ) -> Self

Creates a new ChannelOwner base implementation.

This constructor:

1. Extracts the connection from parent or uses provided connection
2. Creates the channel for RPC communication
3. Stores the initializer data
4. Registers itself in the connection (done by caller via Connection::register_object)
5. Registers itself in parent (done by caller via parent.add_child)

Arguments

• parent - Either a parent ChannelOwner or the root Connection
• type_name - Protocol type name (e.g., “Browser”)
• guid - Unique GUID from server
• initializer - Initial state from __create__ message

pub fn guid(&self) -> &str

Returns the unique GUID for this object.

pub fn type_name(&self) -> &str

Returns the protocol type name.

pub fn parent(&self) -> Option<Arc<dyn ChannelOwner>>

Returns the parent object, if any.

pub fn connection(&self) -> Arc<dyn ConnectionLike>

Returns the connection.

pub fn initializer(&self) -> &Value

Returns the initializer JSON.

pub fn channel(&self) -> &Channel

Returns the channel for RPC.

pub fn dispose(&self, reason: DisposeReason)

Disposes this object and all children recursively.

Arguments

• reason - Why the object is being disposed

pub fn adopt(&self, child: Arc<dyn ChannelOwner>)

Adopts a child object (moves from old parent to this parent).

pub fn add_child(&self, guid: Arc<str>, child: Arc<dyn ChannelOwner>)

Adds a child to this parent’s registry.

pub fn remove_child(&self, guid: &str)

Removes a child from this parent’s registry.

pub fn on_event(&self, method: &str, params: Value)

Handles a protocol event (default implementation logs it).

Subclasses should override this to handle specific events.

pub fn was_collected(&self) -> bool

Returns true if object was garbage collected.

Trait Implementations

impl Clone for ChannelOwnerImpl

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
