read_iter

To any std::io::Read implementor, add also Iterator<Item=u8> implementation.

Installation

In Cargo.toml of your project add:

[dependencies]
read_iter = "0.1"

Examples

let file = File::open("/tmp/test.txt").unwrap();
// "file" implements std::io::Read
let mut it = ReadIter::new(file);
// now "it" also implements std::io::Read
// and "&mut it" implements Iterator<Item=u8>
// "it" has internal buffer, so no need for std::io::BufReader
for byte in &mut it
{	// ...
}
it.take_last_error().unwrap();
