A virtual filesystem for Rust
The virtual file system abstraction generalizes over file systems and allows using
different filesystem implementations (e.g. an in memory implementation for unit tests)
This crate currently has the following implementations:
* **PhysicalFS** - the actual filesystem of the underlying OS
* **MemoryFS** - an ephemeral in-memory file system, intended mainly for unit tests
* **AltrootFS** - a file system with its root in a particular directory of another filesystem
* **OverlayFS** - an overlay file system combining two filesystems, an upper layer with read/write access and a lower layer with only read access
* **EmbeddedFS** - a read-only file system embedded in the executable, requires `embedded-fs` feature
The minimum supported Rust version is 1.32.0.
Comments and pull-requests welcome!
