Struct SortKey 

#[non_exhaustive]
pub struct SortKey {
    pub column: usize,
    pub descending: bool,
    pub nulls_first: bool,
}

One sort key: an input column, a direction, and where its nulls go.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

column: usize

The input column.

descending: bool

Descending order.

nulls_first: bool

Nulls before every value.
