# seekable_reader

This crate introduces the **SeekableReader**, which provides `Seek` if wrapped around a `Read` instance.

An example:

```rust

use std::io::{Read, Seek, SeekFrom};

use seekable_reader::SeekableReader;

let source = vec![1, 2, 3, 4, 5];

let mut reader = SeekableReader::new(source.as_slice(), 1);

let mut buffer = vec![0; 5];

// Read one byte and seek back

reader.read(&mut buffer[..1]).unwrap();

reader.seek(SeekFrom::Start(0)).unwrap();

// First byte can be read again!

let bytes: Vec<_> = reader.bytes().map(|b| b.unwrap()).collect();

assert_eq!(&source, &bytes);

```
