A web server, written in Rust, using actix-web framework.

Web server exposes:

• GET /hello endpoint, and writes name query string value to mongodb as a document({name: $name-query-string}).
• GET /get endpoint which finds one document from db.

• start a mongod deamon locally (mongodb://localhost:27017)
• run cargo build --release
• run ./target/release/rust-mongo-example

GET /hello endpoint will be exposed.

curl http://localhost:3000/hello?name=joe

Success should be returned and {name: "joe"} document should have been written in mydb database, users collection.

In order to see the performance of Rust as a web server with I/O bound tasks, I benchmarked this project against a NodeJS web server(using NestJS) which does the same task. Here are results:

Feel free to contribute, you may want to add extra endpoints, benchmark against different stacks, etc.
