arrow crate does not build with features = ["ffi"] and default_features = false.

[pacman82]

Describe the bug

arrow crate does not build with features = ["ffi"] and default_features = false.

To Reproduce

inculde this in any Cargo.toml

[dependencies]
arrow = { version = "22.0.0", default-features = false, features = ["ffi"] }

yields error

error[E0432]: unresolved import `crate::array::layout`
   --> C:\Users\Markus\.cargo\registry\src\github.aaakk.us.kg-1ecc6299db9ec823\arrow-22.0.0\src\ffi.rs:125:20
    |
125 | use crate::array::{layout, ArrayData};
    |                    ^^^^^^ no `layout` in `array`

Expected behavior

I expected the build to work with only the ffi feature enabled. ffi should then imply all the other features it depends on.

Additional context

Build breaks due to missing layout in this use declaration:

arrow-rs/arrow/src/ffi.rs

Line 125 in 463240a

use crate::array::{layout, ArrayData};

This broke the downstream build of arrow-odbc-py. Default features are enabled in build as a workaround.

This was duplicated to #2659 and was fixed.

My bad, I did only browse the open issues to avoid duplication. Thanks!

No worries. Thanks @pacman82 for reporting this.
