## What it is
Fuser is a Rust library crate for implementing FUSE (Filesystem in Userspace) filesystems. It is a rewrite of the original libfuse C library, providing safe Rust bindings and abstractions for communicating with the kernel FUSE driver.

## Use cases
- implement a custom filesystem in Rust
- mount a virtual filesystem backed by an API or database
- build an encrypted or read-only filesystem for Linux
- expose remote storage as a local mounted filesystem
- prototype kernel-like filesystem behavior in userspace

## When to choose
- you are writing a FUSE filesystem in Rust and want idiomatic, safe APIs
- you need support for newer FUSE kernel ABI versions beyond 7.19
- you want to avoid C libfuse dependencies on Linux

## When to avoid
- you need a FUSE implementation in another language
- you target platforms without FUSE kernel support
- you need a ready-made filesystem rather than a library to build one

## Facets
- artifact type: library
- maturity: active
- function: file-system, developer-tools
- domain: files, operating-systems, developer-tools
- platform: rust
- tags: fuse, filesystems, userspace-filesystem, libfuse, linux, macos
