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
chronofeature is enabled) - format volume
- FAT12, FAT16, FAT32 compatibility
- LFN (Long File Names) extension is supported
- Basic no_std environment support
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.
Add this to your Cargo.toml:
[dependencies]
fatfs = { version = "0.3", features = ["core_io"], default-features = false }
Note: LFN support requires alloc and core_io/collections features and makes use of alloc crate.
You may have to provide a memory allocator implementation.
For building in no_std mode a nightly Rust compiler version compatible with the current core_io crate is required.
See a date string in the core_io dependency version.
