Usage

Library mode (in-process)

use winterbaume_core::MockAws;
use winterbaume_sts::StsService;
use winterbaume_iam::IamService;
use winterbaume_s3::S3Service;

let mock = MockAws::builder()
    .with_service(StsService::new())
    .with_service(IamService::new())
    .with_service(S3Service::new())
    .build();

let config = aws_config::defaults(BehaviorVersion::latest())
    .http_client(mock.http_client())
    .credentials_provider(mock.credentials_provider())
    .region("us-east-1")
    .load()
    .await;

let sts = aws_sdk_sts::Client::new(&config);
let resp = sts.get_caller_identity().send().await.unwrap();
assert_eq!(resp.account(), Some("123456789012"));

Standalone HTTP server

For non-Rust clients, winterbaume-server provides a standalone HTTP server:

cargo run -p winterbaume-server -- --host 127.0.0.1 --port 5555

Point the AWS SDK at it:

export AWS_ENDPOINT_URL=http://localhost:5555
aws s3 mb s3://my-bucket

Architecture

winterbaume-core -- shared infrastructure: MockAws builder, MockService trait, per-account/region state management, HTTP client/connector bridge.
winterbaume-{service} -- each service crate implements MockService with its own protocol handling and in-memory state.
winterbaume-server -- hyper-based HTTP server that registers all service backends.

State is partitioned per account ID and region, matching real AWS isolation semantics.

FAQ

What is the difference between Winterbaume and moto?

Winterbaume targets the Rust AWS SDK directly. It provides an in-process HTTP client for aws-sdk-rust, so tests can run without standing up an external mock service. The project also tracks moto coverage and behaviour closely, and vendors moto as a reference implementation.

When should I use library mode instead of the standalone server?

Use library mode when you are writing Rust tests against aws-sdk-rust and want the fastest setup with no network I/O. Use winterbaume-server when you need to point non-Rust clients, CLIs, or external processes at a mock AWS endpoint over HTTP.

What happens if a service is listed as a stub?

Stub services are routable, but they do not implement service behaviour yet. Requests reach the correct service endpoint shape and then return 501 Not Implemented.

What happens if an operation is not implemented yet?

Behaviour depends on the service. Fully stubbed services return 501 Not Implemented, while partially implemented services only support the operations listed in the coverage table above.

Does Winterbaume keep state between requests?

Yes. State is stored in memory and isolated by account ID and region so repeated SDK calls can observe changes made by earlier requests in the same mock environment.

What is Winterbaume named after?

It is a multilingual pun built around the reference project name moto. "Winter tree" is the literal reading, but the real joke is the sound and imagery of a Japanese pop-culture name hiding in plain sight.
