How do I use the EventReceiver type to get access to the underlying ResponseStream?

[trevorstr]

📦 Crate: aws-sdk-bedrockagentruntime

Objective

I created an Amazon Bedrock Agent in the AWS Management Console, using an OpenAPI spec as input. Next, I wanted to call (invoke) the agent using the AWS SDK for Rust.

Actual Result

The Amazon Bedrock Agent Runtime crate exposes the InvokeAgent API.

The completion field contains the response that I need to access, however it's wrapped up in this EventReceiver type. How do I unwrap the EventReceiver to gain access to the actual ResponseStream? I can't find any way to accomplish this.

Here's the field I need to unwrap: https://docs.rs/aws-sdk-bedrockagentruntime/1.27.0/aws_sdk_bedrockagentruntime/operation/invoke_agent/struct.InvokeAgentOutput.html#structfield.completion

let agent_exec = agent_runtime.invoke_agent()
    .input_text("List all CloudFormation stacks, and then delete all CloudFormation stacks whose names start with a \"t\".")
    .agent_id("trevor")
    .agent_alias_id("V9QIRFYQUF")
    .session_id("session02")
    .send().await;
println!("{0:?}", agent_exec.ok().unwrap().completion); // What do I do with the EventReceiver, after referencing completion field?

Expected Result

I expected there to be an easier API to retrieve results from invoking the Amazon Bedrock Agent that I created.

Hello, to use an EventReceiver, you can refer to this example. The example is for transcribestreaming but the same principle should apply to how to use an EventReceiver.
