Adding feature `array` seems to cause a compile failure

[dhuseby]

I just added the array feature by running cargo add rusqlite --features array and my next compile gave me the following errors:

my current Cargo.toml contains the following dependency line:

rusqlite = { version = "0.31.0", features = ["array"] }

Cheers! 🍻

By default, rusqlite uses SQLite 3.14 API. But sqlite3_result_pointer is only defined after 3.20 (https://sqlite.org/bindptr.html):

Three new "_pointer()" interfaces were added to SQLite 3.20.0 (2017-08-01)

So you need to add either bundled or buildtime_bindgen feature.
