Three layers of API are provided:

• mod ffi provides exhaustive, though unsafe, bindgen bindings for libsqlite.h
• mod core provides a minimal safe interface to the basic sqlite3 API
• mod types provides ToSql/FromSql traits, and the library provides convenient query() and update() APIs.

The API design is perhaps stabilizing, though testing is uneven and I have not used the library beyond trivial integration tests.

TODO

• another thorough read-through of the sqlite API intro, with unit tests to match; especially...
  • unit testing other than the happy-paths
• ToSql/FromSql can now be implemented by clients, but the types module probably doesn't hit the 80% mark yet; e.g. it's missing uint and &[u8].
• investigate test coverage tools for rust
• basic benchmarking

Motivation and Acknowledgements

I was looking into sandstorm, a personal cloud platform with an architecture based on the wonderful capability security paradigm, and I found a rust application, acronymy, that uses the native API rather than the traditional POSIX environment.

I started poring over the code and followed the dependency link to linuxfood's rustsqlite. I started working on a memory safety issue etc. but soon found a number of large-scale API design issues that I wasn't sure how to approach with the upstream developers. I was also inspired by FromSql, ToSql and such from sfackler's rust-postgres API.

So I started from scratch, using bindgen, Result (sum types) etc.
