random-access-storage

Abstract interface to implement random-access instances.

• Documentation
• Crate

Why?

This module forms a shared interface for reading and writing bytes to different backends. By having a shared interface, it means implementations can easily be swapped, depending on the environment.

Usage

```rust extern crate randomaccessstorage;

use randomaccessstorage::{RandomAccessMethods, RandomAccess};

struct S; impl RandomAccessMethods for S { type Error = std::io::Error;

fn open(&mut self) -> Result<(), Self::Error> { unimplemented!(); }

fn write(&mut self, offset: u64, data: &[u8]) -> Result<(), Self::Error> { unimplemented!(); }

fn read(&mut self, offset: u64, length: u64) -> Result, Self::Error> { unimplemented!(); }

fn readtowriter( &mut self, offset: u64, length: u64, writer: &mut impl std::io::Writer ) -> Result<(), Self::Error> { unimplemented!(); }

fn del(&mut self, offset: u64, length: u64) -> Result<(), Self::Error> { unimplemented!(); }

fn truncate(&mut self, length: u64) -> Result<(), Self::Error> { unimplemented!(); } }

let _file = RandomAccess::new(S); ```
