rust-pg

Playing with rust and postgres. This was my first rust codebase and everything I know starts with reading https://doc.rust-lang.org/stable/book. if you know rust or what a real application don't look here.

Quick Start

brew install rust; #install rust stable
git clone git@github.com:amichal/rust-pg.git;
cd rust-pg;
cargo run # build any missing our out of date binaries to `target/debug/...` and then run the main package (listed in Cargo.toml)
# or
cargo run --release

Like tests?

Rust encourages including test code right in your src. cargo test will find and run all test functions and report on thier ruslts

Notes for rails devs

• src/main.rs is the actual rust code and has inline comments. After skimming it you should probaby go read the rust docs if you are still interested.
• Cargo.toml is like a Gemfile or .gemspec. See also Cargo.lock. https://crates.io/ ~= https://rubygems.org/
• RustConfig and Procfile support heroku create --buildpack https://github.com/emk/heroku-buildpack-rust.git which is used to deploy to heroku. This is currently inefficent as hell as it uploads all the source to heroku and rebuilds all the dependancies from sctrach on each git push heroku master. THe buildpack could be enhanced to cache the build directory and then only copy the release binaries etc to the dynos... bit it works for now. Basically I followed https://github.com/emk/heroku-rust-cargo-hello
• This currently uses https://github.com/iron/iron as a web framework and https://github.com/sfackler/rust-postgres for talking to postgres. I want to try out https://github.com/nickel-org/nickel.rs as well and some of the ORMs and db abstraction layers
• Next up for exploration are HTML templating. https://github.com/jeremyletang/rust-haml exists but since my goal is to explore more efficent pre-compiled web stack runtimes I really want to try https://github.com/lfairy/maud which does the template compilation at runtime and doesn't need to have everything turned into a heap allocated HashMap
