cargo +nightly b --release
To enable parallelism, enable the parallelism feature:
cargo +nightly b --release --features parallelism
To create a NRFS filesystem, use the tool binary:
fallocate -l 16M /tmp/nrfs.img
# Without files
./target/release/tool make /tmp/nrfs.img
# With files copied
./target/release/tool make /tmp/nrfs.img -d /directory/to/copy
To check if the filesystem was properly created, use tool dump /tmp/nrfs:
$ ./target/release/tool dump /tmp/nrfs

If you use a UNIX-based system (e.g. Linux, macOS, FreeBSD) you can use the FUSE driver.
Mount with:
mkdir /tmp/nrfs
./target/release/fuse /tmp/nrfs.img /tmp/nrfs
Unmount with:
fusermount -u /tmp/mnt
