Storage backend to be used by ClientDatabase

Required Methods

fn num_pages(&self) -> u32

Total number of pages available for reads/writes

fn read( &self, buffer: Vec<AlignedPage>, length: u32, offset: u32, ) -> Receiver<Result<Vec<AlignedPage>>>

Reading into aligned memory.

length is the number of AlignedPage units (pages) to read into (append to) buffer. offset is in pages too.

fn write( &self, buffer: Vec<AlignedPage>, offset: u32, ) -> Receiver<Result<Vec<AlignedPage>>>

Writing from aligned memory.

offset is in AlignedPage units (pages). After successful writing returns allocated pages back to the caller.
