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

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

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

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

Returns the length of the file.

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

Check if the file exists.

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 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.

impl ManagedFileOpener<MemoryFile> for MemoryFileManager

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