Abstract interface to implement random-access instances.
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.
```rust,ignore extern crate randomaccessstorage; use randomaccessstorage::{Error, Sync, SyncMethods};
struct S; impl SyncMethods for S { fn open(&self) -> Result<(), Error> { // ... } fn write(&self, offset: u64, data: &[u8]) -> Result<(), Error> { // ... } fn read(&self, offset: u64, length: u64) -> Result<&[u8], Error> { // ... } fn del(&self, offset: u64, length: u64) -> Result<(), Error> { // ... } }
let file = Sync::new(SyncMethods); file.write(0, b"hello")?; file.write(0, b" world")?; let text = file.read(0, 11,)?; assert!(text, b"hello world"); ```
