Struct PublishHandle 

pub struct PublishHandle { /* private fields */ }

A handle that represents an in-flight publish operation.

This struct is a Future. You can .await it to get the final result of the publish call: either a server-assigned message ID String or an Error if the publish failed.

A PublishHandle is returned from every call to Publisher::publish

Example

// publish() returns a handle immediately.
let handle = publisher.publish(PubsubMessage::new().set_data("hello world"));

// The handle can be awaited later to get the result.
match handle.await {
    Ok(message_id) => println!("Message published with ID: {message_id}"),
    Err(e) => eprintln!("Failed to publish message: {e:?}"),
}

Trait Implementations

impl Future for PublishHandle

type Output = Result<String, Error>

The result of the publish operation.

• Ok(String): The server-assigned message ID.
• Err(Error): An error indicating the publish failed.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
