Rust FAT FS

Travis Build Status MIT licensed crates.io Documentation Minimum rustc version

A FAT filesystem library implemented in Rust.

Features: * read/write file using standard Read/Write traits * read directory contents * create/remove file or directory * rename/move file or directory * read/write file timestamps (updated automatically if chrono feature is enabled) * format volume * FAT12, FAT16, FAT32 compatibility * LFN (Long File Names) extension is supported * Basic no_std environment support

Usage

Add this to your Cargo.toml:

[dependencies]
fatfs = "0.3"

and this to your crate root:

extern crate fatfs;

You can start using the fatfs library now:

let img_file = File::open("fat.img")?;
let fs = fatfs::FileSystem::new(img_file, fatfs::FsOptions::new())?;
let root_dir = fs.root_dir();
let mut file = root_dir.create_file("hello.txt")?;
file.write_all(b"Hello World!")?;

Note: it is recommended to wrap the underlying file struct in a buffering/caching object like BufStream from fscommon crate. For example:

extern crate fscommon;
let buf_stream = BufStream::new(img_file);
let fs = fatfs::FileSystem::new(buf_stream, fatfs::FsOptions::new())?;

See more examples in the examples subdirectory.

no_std usage

Add this to your Cargo.toml:

[dependencies]
fatfs = { version = "0.3", features = ["core_io"], default-features = false }

For building in no_std mode a Rust compiler version compatible with core_io crate is required.

For now core_io supports only nightly Rust channel. See a date suffix in latest core_io crate version for exact compiler version.

Additional features:

Note: above feature is enabled by default.
