Implementations

impl Sync

pub fn new(fd: RawFd, datasync: bool) -> Self

Create Sync.

If datasync is true, the file metadata may not be synchronized.

Platform specific

• IOCP: it is synchronized operation, and calls FlushFileBuffers.
• io-uring: fdatasync if datasync specified, otherwise fsync.
• polling: it is synchronized fdatasync or fsync.
