Struct FileSystem

pub struct FileSystem<S>
where
    S: Read + Write + Seek,
{ /* private fields */ }

An API to process a FAT filesystem

Implementations

impl<S> FileSystem<S>

where S: Read + Write + Seek,

Getter functions

pub fn fat_type(&self) -> FATType

What is the FATType of the filesystem

impl<S> FileSystem<S>

where S: Read + Write + Seek,

Public functions

pub fn from_storage(storage: S) -> FSResult<Self, S::Error>

Create a FileSystem from a storage object that implements Read, Write & Seek

Fails if the storage is way too small to support a FAT filesystem. For most use cases, that shouldn’t be an issue, you can just call .unwrap()

pub fn read_dir(&mut self, path: PathBuf) -> FSResult<Vec<DirEntry>, S::Error>

Read all the entries of a directory (PathBuf) into Vec<DirEntry>

Fails if path doesn’t represent a directory, or if that directory doesn’t exist

pub fn get_file(&mut self, path: PathBuf) -> FSResult<File<'_, S>, S::Error>

Get a corresponding File object from a PathBuf

Borrows &mut self until that File object is dropped, effectively locking self until that file closed

Fails if path doesn’t represent a file, or if that file doesn’t exist

Trait Implementations

impl<S> Debug for FileSystem<S>

where S: Read + Write + Seek + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
