Crate vfs

Virtual file system abstraction

The virtual file system abstraction generalizes over file systems and allow using different filesystem implementations (i.e. an in memory implementation for unit tests)

A virtual filesystem consists of three basic types

• Paths - locations in the filesystem
• File - actual file contents (think inodes)
• Metadata - metadata information about paths

This crate currently has the following implementations:

• PhysicalFS - the actual filesystem of the underlying OS
• MemoryFS - an ephemeral in-memory implementation (intended for unit tests)

Re-exports

pub use physical::PhysicalFS;

pub use altroot::AltrootFS;

pub use memory::MemoryFS;

Modules

altroot	A "physical" file system implementation using the underlying OS file system, with its root in a particular directory. Similar to a chroot but done purely by path manipulation; thus, it's harder to guarentee that it's impossible for a malicious user to escape the given directory.
memory	An ephemeral in-memory file system, intended mainly for unit tests
physical	A "physical" file system implementation using the underlying OS file system
util	Utility functions for working with the virtual file systems

Structs

Traits

Functions
