sqs-extended-client-rust

THIS REPO IS A WIP

sqs-extended-client-rust is an extension to the Amazon SQS Client that enables sending and receiving messages up to 2GB via Amazon S3. It is very similar to the SQS Extended Client for Java, but has an adjusted API to be more Rust friendly.

Installation

cargo add sqs-extended-client

Usage

use aws_config::BehaviorVersion;
use aws_sdk_sqs::operation::{receive_message::{builders::ReceiveMessageFluentBuilder, ReceiveMessageOutput}, send_message::builders::SendMessageFluentBuilder};
use sqs_extended_client::{SqsExtendedClient, SqsExtendedClientBuilder, SqsExtendedClientError};

#[::tokio::main]
async fn main() -> Result<(), SqsExtendedClientError> {
    // get a sqs_queue_url & s3_bucket_name
    let sqs_queue_url: String = "rusty-extended-queue".to_string();
    let s3_bucket_name: String = "rusty-bucket".to_string();

    // create an aws_config
    let config: aws_config::SdkConfig =
        aws_config::load_defaults(BehaviorVersion::v2025_01_17()).await;

    // create an s3 client
    let s3_client: aws_sdk_s3::Client = aws_sdk_s3::Client::new(&config);

    // create an sqs client
    let sqs_client: aws_sdk_sqs::Client = aws_sdk_sqs::Client::new(&config);

    // use the SqsExtendedClientBuilder to create a SqsExtendedClient
    let sqs_extended_client: SqsExtendedClient =
        SqsExtendedClientBuilder::new(s3_client, sqs_client.clone())
            .with_s3_bucket_name(s3_bucket_name)
            .build();

    // Create a large message of size 12MiB
    let large_message: String = "X".repeat(12 * 1024 * 1024);

    // Create a "send message request" 
    let msg_input: SendMessageFluentBuilder = sqs_client
        .send_message()
        .queue_url(&sqs_queue_url)
        .message_body(large_message);
    
    // Sqs Extended Client Send message
    sqs_extended_client.send_message(msg_input).await?;

    // Create a "receive message request" 
    let receive_msg: ReceiveMessageFluentBuilder = sqs_client.receive_message().queue_url(sqs_queue_url);

    // Sqs Extended Client Receive message
    let rcv:ReceiveMessageOutput = sqs_extended_client.receive_message(receive_msg).await?;

    // Print the large message:
    for message in rcv.messages.unwrap_or_default() {
        println!("Got the message: {:#?}", message);
    }

    // There is also: 

    // sqs_extended_client.delete_message
    // sqs_extended_client.change_message_visibility

    // and many options in the SqsExtendedClientBuilder

    Ok(())

RoadMap

v1.X.X

• .to_string() & .clone()
• marshall_json -> serde
• async handling of rcv_msg
• rustify parse_extended_receipt_handle
• mocked public/non-pure fns

v2.X.X

• receive message, msg attr names = "ALL" -> consider enabling
• Add Batch functions
• Deal with SQS & Lambda events
