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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
