Struct sunrise_fs::detail::driver::fat::directory::DirectoryInterface

pub struct DirectoryInterface {
    base_path: ArrayString<[u8; 768]>,
    inner_fs: Arc<Mutex<FatFileSystem<Box<dyn StorageDevice<Error = Error> + Send>>>>,
    internal_iter: FatDirectoryEntryIterator,
    filter_fn: fn(_: &FatDirectoryEntry) -> bool,
    entry_count: u64,
}

A libfat directory reader implementing DirectoryOperations.

Fields

base_path: ArrayString<[u8; 768]>

The opened directory path. Used to get the complete path of every entries.

inner_fs: Arc<Mutex<FatFileSystem<Box<dyn StorageDevice<Error = Error> + Send>>>>

libfat filesystem interface.

internal_iter: FatDirectoryEntryIterator

The iterator used to iter over libfat's directory entries.

filter_fn: fn(_: &FatDirectoryEntry) -> bool

The filter required by the user.

entry_count: u64

The number of entries in the directory after filter_fn.

Implementations

impl<'a> DirectoryInterface

pub fn new(
    base_path: ArrayString<[u8; 768]>,
    inner_fs: Arc<Mutex<FatFileSystem<Box<dyn StorageDevice<Error = Error> + Send>>>>,
    internal_iter: FatDirectoryEntryIterator,
    filter_fn: fn(_: &FatDirectoryEntry) -> bool,
    entry_count: u64
) -> Self

Create a new DirectoryInterface.

fn convert_entry(
    fat_dir_entry: FatDirectoryEntry,
    base_path: &ArrayString<[u8; 768]>
) -> LibUserResult<DirectoryEntry>

convert libfat's DirectoryEntry to libfs's DirectoryEntry.
