    parent: u64,
    child: u64,
    name: impl AsRef<OsStr>
) -> Result<()>

Notify that an entry with the specified name has been deleted from the directory.

pub async fn store<'_, '_, '_>(
    &'_ mut self,
    ino: u64,
    offset: u64,
    data: &'_ [&'_ [u8]]
) -> Result<()>

Replace the specified range of cache data with a new value.

pub async fn retrieve<'_>(
    &'_ mut self,
    ino: u64,
    offset: u64,
    size: u32
