Crate srfs_core

Simple Rust File System (core library)

A simple filesystem impremented in Rust [no_std].

This crate is a work-in-progress. It contains low-level code to work directly with block devices (see trait SyncBlockDevice).

Higher-level API, dependent on [std], lives in crate srfs.

All basic filesystem features are implemented (see struct SyncFileSystem), with provisions for extensions.

At the moment only synchronous interface is provided. See src/tests.rs for usage examples.
