Tracking issues of goal: Make ofs running!

[Xuanwo]

This issue is used to track our goal that making ofs running!

Introduction

ofs is a userspace filesystem that powered by opendal. We expect user can mount a opendal storage services locally as a fs for read and write. Our goal is not to implement a full-fledged filesystem. We will implement features based on opendal's design and services capabilities.

Related ideas:

• feat: Add a userspace filesystem backed by OpenDAL #3411
• feat: oay fuse frontend support #2625

Similiar projects:

• https://github.com/awslabs/mountpoint-s3

Tasks

• Implement the layout of fuser::Filesystem
• Add CI workflow
• Add README and CONTIBUTING guide

Created #3857 based on fuse3(v0.6.1, latest released version).

It's really nice to have the built-in inode <=> directory mapping, so we can leverage the feature and only implement the interactions with OpenDAL, based on PathFilesystem trait.

However, there are a lot of errors under rustc 1.73.0 (cc66ad468 2023-10-03) due to the async runtime and some other issues.

Would you like to take a look, which async runtime is preferred? @oowl @ho-229

I temporarily use tokio-async runtime in the mentioned branch.

I'm sorry for not getting back to you sooner. Yeah, OpenDAL recommends using tokio as async runtime in some need cases.
