Struct Notifier

pub struct Notifier { /* private fields */ }

Implementations

impl Notifier

pub fn inval_inode(&self, ino: u64, off: i64, len: i64) -> Result<()>

Notify the cache invalidation about an inode to the kernel.

pub fn inval_entry<T>(&self, parent: u64, name: T) -> Result<()>

where T: AsRef<OsStr>,

Notify the invalidation about a directory entry to the kernel.

pub fn delete<T>(&self, parent: u64, child: u64, name: T) -> Result<()>

where T: AsRef<OsStr>,

Notify the invalidation about a directory entry to the kernel.

The role of this notification is similar to notify_inval_entry. Additionally, when the provided child inode matches the inode in the dentry cache, the inotify will inform the deletion to watchers if exists.

pub fn store<T>(&self, ino: u64, offset: u64, data: T) -> Result<()>

where T: Bytes,

Push the data in an inode for updating the kernel cache.

pub fn retrieve(&self, ino: u64, offset: u64, size: u32) -> Result<u64>

Retrieve data in an inode from the kernel cache.

pub fn poll_wakeup(&self, kh: u64) -> Result<()>

Send I/O readiness to the kernel.
