|
|
* Basic no_std environment support.

Usage
|
|
-----
|
|
|
|
Put this in your `Cargo.toml`:
|
|
|
|
[dependencies]
|
|
fatfs = "0.2"
|
|
|
|
Put this in your crate root:
|
|
|
|
extern crate fatfs;
|
|
|
|
You can start using library now:
|
|
|
|
let img_file = File::open("fat.img").unwrap();
|
|
let mut buf_stream = fatfs::BufStream::new(img_file);
|
|
let fs = fatfs::FileSystem::new(&mut buf_stream, fatfs::FsOptions::new()).unwrap();
|
|
let mut root_dir = fs.root_dir();
|
|
let mut file = root_dir.create_file("hello.txt").unwrap();
|
|
file.write_all(b"Hello World!").unwrap();
|
|
|
|
See more examples in `examples` subdirectory.
|
|
|
|
no_std usage
|
|
------------
|
|
|
|
Put this in your `Cargo.toml`:
|
|
|
|
[dependencies]
|
|
fatfs = { version = "0.2", 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 nightly Rust version compatible with current `core_io` crate is required.
|
|
See date string in `core_io` dependency version.
