`concat-reader` is a library for Rust that contains utility functions and traits to create

concatenated [`Read`] objects from any thing that implements [`IntoIterator`].

```rust

  use concat_reader::{FileConcatRead, concat_path};

  use std::io::{self, Read, BufRead, BufReader, Write};

  fn main() -> io::Result<()>{

      let files = vec!["/path/to/file_1", "/path/to/file_2", "/path/to/file_3"];

      let mut f = concat_path(files);

      let mut buffered = BufReader::new(f);

      let stdout = io::stdout();

      let mut handle = stdout.lock();

      loop {

          let mut line = String::new();

          let r = buffered.read_line(&mut line)?;

          if r == 0 {

              return Ok(())

          }

          let f = buffered.get_ref().file_path();

          eprintln!("read from {:?}", f);

          handle.write(line.as_bytes())?;

      }

  }

```
