I think I answered your question in my comment, no? It'll make cross platform builds easier instead of the current steps needed for FFI libraries. My experience with cross platform FFI builds are slim but last time I tried it, it was painful (versus Rust handling it all with the right toolchain).

Can't be as hard as reimplementing SQLite, can it?

But reimplementing SQLite can be done by somebody else, whereas dealing with FFI must be done by me.

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).
