nfd-rs is a Rust binding to the library nativefiledialog, that provides a convenient cross-platform interface to opening file dialogs on Linux, OS X and Windows.

This crate has been tested on Mac, Window and Linux (Ubuntu 14.04) and supports single/mutliple and save dialogs, notice APIs may break with newer versions.

• Add the dependency nfd in your Cargo.toml

  [dependencies]
  nfd = "0.0.4"

• Open a single file dialog

  extern crate nfd;
  
  use nfd::Response;
  
  fn main() {
  
    let result = nfd::open_file_dialog(None, None).unwrap_or_else(|e| {
    	panic!(e);
    });
  
    match result {
        Response::Okay(file_path) => println!("File path = {:?}", file_path),
        Response::OkayMultiple(files) => println!("Files {:?}", files),
        Response::Cancel => println!("User canceled"),
    }
  }

• Open a multi file dialog using builder with jpg files as filter

  extern crate nfd;
  
  use nfd::Response;
  
  fn main() {
  
    let result = nfd::dialog_multiple().filter("jpg").open().unwrap_or_else(|e| {
    	panic!(e);
    });
  
    match result {
        Response::Okay(file_path) => println!("File path = {:?}", file_path),
        Response::OkayMultiple(files) => println!("Files {:?}", files),
        Response::Cancel => println!("User canceled"),
    }
  }
