pub enum AnyFileManager {
    Std(StdFileManager),
    Memory(MemoryFileManager),
}

Performs copy-assignment from source.

impl Debug for AnyFileManager

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

Formats the value using the given formatter.

impl Default for AnyFileManager

fn default() -> Self

Returns the “default value” for a type.

impl FileManager for AnyFileManager

type File = AnyFile

The type of file managed by this manager.

type FileHandle = AnyFileHandle

A file handle type, which can have operations executed against it.

fn read(&self, path: impl AsRef<Path>) -> Result<Self::FileHandle, Error>

Returns a file handle that can be used for reading operations.

fn append(&self, path: impl AsRef<Path>) -> Result<Self::FileHandle, Error>

Returns a file handle that can be used to read and write.

fn close_handles<F: FnOnce(u64)>(
    &self,
    path: impl AsRef<Path>,
    publish_callback: F
)

Closes all open handles for path, and calls publish_callback before unlocking any locks aquired during the operation.

fn delete(&self, path: impl AsRef<Path>) -> Result<bool, Error>

Check if the file exists.

fn delete_directory(&self, path: impl AsRef<Path>) -> Result<(), Error>

Removes a directory and all of its contents.

fn exists(&self, path: impl AsRef<Path>) -> Result<bool, Error>

Check if the file exists.

fn file_length(&self, path: impl AsRef<Path>) -> Result<u64, Error>

Returns the length of the file.

impl ManagedFileOpener<AnyFile> for AnyFileManager

fn open_for_read(
    &self,
    path: impl AsRef<Path> + Send,
    id: Option<u64>
) -> Result<AnyFile, Error>

Opens a file at path with read-only permission.

fn open_for_append(
    &self,
    path: impl AsRef<Path> + Send,
    id: Option<u64>
) -> Result<AnyFile, Error>

Opens or creates a file at path, positioning the cursor at the end of the file.
