You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/perseus/packages/perseus-warp/src
    
    the code of the file until where you have to start completion: #![doc = include_str!("../README.proj.md")]

## Packages

This is the API documentation for the `perseus-warp` package, which allows Perseus apps to run on Warp. Note that Perseus mostly uses [the book](https://framesurge.sh/perseus/en-US) for
documentation, and this should mostly be used as a secondary reference source. You can also find full usage examples [here](https://github.com/framesurge/perseus/tree/main/examples).
