pub struct FileOperations {}

Implementations

impl FileOperations

pub async fn open_path( data_dir: &Path, page_id: &PageId, file_number: usize, ) -> Result<File, FileOperationsError>

pub async fn add_chunk( file: &mut File, page_offset: &PageOffset, buffer: Bytes, ) -> Result<(), FileOperationsError>

Note the File Handle AND PageOffset should point to where the add should occur If the file is larger than requested nothing is done.

pub async fn make_sub_path( data_dir: &Path, page_id: &PageId, ) -> Result<PathBuf, FileOperationsError>

pub async fn read_chunk( file: &mut File, page_offset: &PageOffset, ) -> Result<Bytes, FileOperationsError>

pub async fn update_chunk( file: &mut File, page_offset: &PageOffset, buffer: Bytes, ) -> Result<(), FileOperationsError>
