Implementations

impl PageAllocator

pub fn new(high_water_mark: u32) -> Self

pub fn allocate(&mut self) -> PageId

Prefers reusing reclaimed pages over incrementing the high water mark.

pub fn free(&mut self, page_id: PageId)

Not immediately reusable - goes into pending-free list.

pub fn high_water_mark(&self) -> u32

pub fn freed_this_txn(&self) -> &[PageId]

pub fn add_ready_to_use(&mut self, pages: Vec<PageId>)

pub fn commit(&mut self) -> Vec<PageId>

pub fn rollback(&mut self)

pub fn ready_count(&self) -> usize

pub fn freed_count(&self) -> usize
