Required Methods

fn materialize(&self, _: Vec<Self::PartialPage>) -> Self::MaterializedPage

Used to generate the result of get requests on the PageCache

fn consolidate(&self, _: Vec<Self::PartialPage>) -> Vec<Self::PartialPage>

Used to compress long chains of partial pages into a condensed form during compaction.

fn recover(&mut self, _: Self::MaterializedPage) -> Option<Self::Recovery>

Used to feed custom recovery information back to a higher-level abstraction during startup. For example, a B-Link tree must know what the current root node is before it can start serving requests.
