tokio-file-futures 0.1.0

Some basic futures on top of tokio-fs's polled file operations

File Futures

This crate provides the Futures abstraction around many of the poll methods provided in tokio-fs.


Add the dependencies in Cargo.toml

# Cargo.toml

tokio-file-futures = "0.1"
tokio-fs = "0.1"
// src/

extern crate file_futures;
extern crate futures;
extern crate tokio_fs;


use std::io::SeekFrom;

use file_futures::AsyncFile;
use futures::Future;
use tokio_fs::File;

fn main() {
    let future = File::create("/tmp/some-tmpfile")
        .map_err(|e| println!("Create Error {}", e))
        .and_then(|_| {
            let future1 = File::open("/tmp/some-tmpfile")
                .and_then(|file| file.metadata().and_then(|(_file, _metadata)| Ok(())))
                .map_err(|e| println!("Error1: {}", e));

            let future2 = File::open("/tmp/some-tmpfile")
                .and_then(|file| {
                        .and_then(|(_file, _from_start)| Ok(()))
                .map_err(|e| println!("Error2: {}", e));


    tokio::run(|_| ()));
