Lib.rs

The limiting-factor crate offers facilities to implement a REST API.

Goal

The goal of this library is to provide:

• glue code for Rocket and Diesel
• standard API replies
• boilerplate to parse environment to extract configuration and run a server

That allows an API or a back-end web server to focus on requests and data model, and to maintain helper methods as a separate library.

Dependencies

• Diesel, as PostgreSQL ORM, with r2d2 support to pool connections
• Rocket, as web framework
• Chrono, for date and time types

Compile

Windows

You need to give to rustc some hints about where libpq.lib is.

The pq-sys crate offers a build script to find the library and then print the relevant hints.

You can manually set your PostgreSQL library folder with:

export PQ_LIB_DIR="C:\Program Files\PostgreSQL\13\lib"
cargo run
