Struct AnyFileStorage 

pub struct AnyFileStorage { /* private fields */ }

Alternative to SimpleFileStorage that uses multiple SimpleFileStorages to allow parallel reads by different threads.

Implementations

impl AnyFileStorage

pub fn new(filename: &str) -> Box<Self>

Create new.

Trait Implementations

impl BasicStorage for AnyFileStorage

fn size(&self) -> u64

Get the size of the underlying storage. Note : this is valid initially and after a commit but is not defined after write is called.

fn read(&self, off: u64, bytes: &mut [u8])

Read data.

fn write(&mut self, off: u64, bytes: &[u8])

Write byte slice to storage.

fn commit(&mut self, size: u64)

Finish write transaction, size is new size of underlying storage.

fn clone(&self) -> Box<dyn Storage>

Clone. note: provided method panics.

fn write_vec(&mut self, start: u64, data: Vec<u8>)

Write byte Vec.

fn write_data(&mut self, start: u64, data: Data, off: usize, len: usize)

Write Data slice.

fn write_u64(&mut self, start: u64, value: u64)

Write u64.

fn read_u64(&self, start: u64) -> u64

Read u64.

fn wait_complete(&self)

Wait until current writes are complete.
