I feel like I must be misunderstanding you... why would the FFI be done by you? The rusqlite crate provides wrappers you can use, and there are probably other wrapper crates that I haven't looked at.

But I have to configure how it finds SQLite. Sure, SQLite specifically is fairly easy – I only need to enable the "bundled" crate feature and make sure my Clang version matches the Rust version so LTO works – but it's a little arcane to use Cargo with any non-Rust package in the dependency chain. Cargo Just Works™. Cargo with C FFI doesn't.

Thanks for the explanation!

Not the parent comment, but I believe they're referring to the cross compilation aspects which wouldn't be resolved by just using the rusqlite crate (I use rusqlite and have this issue).
