Bindgen trying to derive default for types that can't be.

[hcldan]

pub __bindgen_padding_0: [u8; 40usize], | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the trait Default is not implemented for [u8; 40]

This very well may be something I (should) have to work around, but could you please explain the meaning of "when possible" in the doc?
