Enum PageKind 

#[non_exhaustive]
pub enum PageKind {
    Dictionary,
    Data,
    ColumnChunk,
}

What a PlannedRange contains.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dictionary

The dictionary page of a column chunk.

Data

One data page.

ColumnChunk

A complete column chunk. The plan uses this when the column has no offset index, so page locations are unknown.
