Struct StackDB

pub struct StackDB<'l, A: Allocator<'l>> { /* private fields */ }

Implementations

impl<'l, A: Allocator<'l>> StackDB<'l, A>

pub fn new(alloc: A) -> Result<Self, Error>

creates a database interface; either loads an existing db or creates a new one.

pub fn read(&mut self, addr: Range<u64>) -> Result<Box<[u8]>, Error>

Reads data from either the heap or disk layers

pub fn rebase(&mut self, buffer_size: u64) -> Result<(), Error>

Rebases and drops overwritten layers (the database history) by compressing all the layers into one to save space

Warning: will temporarity double database size

pub fn write(&mut self, addr: u64, data: &[u8]) -> Result<(), Error>

Writes data to the heap layer (collisions are fine) (flush to commit the heap layers to disk)

pub fn commit(&mut self) -> Result<(), Error>

Commits / writes the read-write layer’s (on the heap) writes to the database (on the disk); making it read-only
