A Web Server in Rust

Implementations

1. multithread (threadpool): on branch master
2. async (tokio): on branch tokio

Features

1. High concurrency (as shown in section Performance Summary)
2. multiply methods supported(POST, GET), along with various services(echo, file IO, etc.)
3. modular architecture (as abstracted into request and response mods)

Serving Endpoionts

• GET

  • /: return 200 with empty body

    

  • /echo: echo whatever comes after it

    

  • /user-agent: return 200 with user-agent

  • /files: fetch files from the assigned directory on server side. (set when running with cargo run -- --directory <root-dir>), invalid path get a 404.

    

• POST

  • /files: create a file using body as its content, get 201 when succeeded, 500 when failed
