//! This crate provides a FUSE-based, non-generic filesystem that I/O is authenticated. This
//! filesystem assumes the storage layer is not trusted, e.g. file is provided by an untrusted VM,
//! and the content can't be simply trusted. The filesystem can use its public key to verify a
//! (read-only) file against its associated fs-verity signature by a trusted party. With the Merkle
//! tree, each read of file block can be verified individually.
//!
//! The implementation is not finished.
