Struct inotify::WatchMask

pub struct WatchMask { /* fields omitted */ }

Describes a file system watch

Passed to Inotify::add_watch, to describe what file system events to watch for, and how to do that.

Examples

WatchMask constants can be passed to Inotify::add_watch as is. For example, here's how to create a watch that triggers an event when a file is accessed:

inotify.add_watch("/tmp/inotify-rs-test-file", WatchMask::ACCESS)
   .expect("Error adding watch");

You can also combine multiple WatchMask constants. Here we add a watch this is triggered both when files are created or deleted in a directory:

inotify.add_watch("/tmp/", WatchMask::CREATE | WatchMask::DELETE)
   .expect("Error adding watch");

Methods

impl WatchMask

const ACCESS: WatchMask

ACCESS: WatchMask = WatchMask{bits: ffi::IN_ACCESS,}

File was accessed

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_ACCESS.

const ATTRIB: WatchMask

ATTRIB: WatchMask = WatchMask{bits: ffi::IN_ATTRIB,}

Metadata (permissions, timestamps, ...) changed

When watching a directory, this event can be triggered for the directory itself, as well as objects inside the directory.

See inotify_sys::IN_ATTRIB.

const CLOSE_WRITE: WatchMask

CLOSE_WRITE: WatchMask = WatchMask{bits: ffi::IN_CLOSE_WRITE,}

File opened for writing was closed

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_CLOSE_WRITE.

const CLOSE_NOWRITE: WatchMask

CLOSE_NOWRITE: WatchMask = WatchMask{bits: ffi::IN_CLOSE_NOWRITE,}

File or directory not opened for writing was closed

When watching a directory, this event can be triggered for the directory itself, as well as objects inside the directory.

See inotify_sys::IN_CLOSE_NOWRITE.

const CREATE: WatchMask

CREATE: WatchMask = WatchMask{bits: ffi::IN_CREATE,}

File/directory created in watched directory

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_CREATE.

const DELETE: WatchMask

DELETE: WatchMask = WatchMask{bits: ffi::IN_DELETE,}

File/directory deleted from watched directory

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_DELETE.

const DELETE_SELF: WatchMask

DELETE_SELF: WatchMask = WatchMask{bits: ffi::IN_DELETE_SELF,}

Watched file/directory was deleted

See inotify_sys::IN_DELETE_SELF.

const MODIFY: WatchMask

MODIFY: WatchMask = WatchMask{bits: ffi::IN_MODIFY,}

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_MODIFY.

See inotify_sys::IN_MOVE_SELF.

const MOVED_FROM: WatchMask

MOVED_FROM: WatchMask = WatchMask{bits: ffi::IN_MOVED_FROM,}

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_MOVED_FROM.

const MOVED_TO: WatchMask

MOVED_TO: WatchMask = WatchMask{bits: ffi::IN_MOVED_TO,}

File was renamed/moved; watched directory contains new name

When watching a directory, this event is only triggered for objects inside the directory, not the directory itself.

See inotify_sys::IN_MOVED_TO.

const OPEN: WatchMask

OPEN: WatchMask = WatchMask{bits: ffi::IN_OPEN,}

File or directory was opened

When watching a directory, this event can be triggered for the directory itself, as well as objects inside the directory.

See inotify_sys::IN_OPEN.

• ATTRIB
• CLOSE_WRITE
• CLOSE_NOWRITE
• CREATE
• DELETE
• DELETE_SELF
• MODIFY
• MOVE_SELF
• MOVED_FROM

See inotify_sys::IN_CLOSE.

const DONT_FOLLOW: WatchMask

DONT_FOLLOW: WatchMask = WatchMask{bits: ffi::IN_DONT_FOLLOW,}

Don't dereference the path if it is a symbolic link

See inotify_sys::IN_DONT_FOLLOW.

const EXCL_UNLINK: WatchMask

EXCL_UNLINK: WatchMask = WatchMask{bits: ffi::IN_EXCL_UNLINK,}

Filter events for directory entries that have been unlinked

See inotify_sys::IN_EXCL_UNLINK.

const MASK_ADD: WatchMask

MASK_ADD: WatchMask = WatchMask{bits: ffi::IN_MASK_ADD,}

If a watch for the inode exists, amend it instead of replacing it

See inotify_sys::IN_MASK_ADD.

const ONESHOT: WatchMask

ONESHOT: WatchMask = WatchMask{bits: ffi::IN_ONESHOT,}

Only receive one event, then remove the watch

See inotify_sys::IN_ONESHOT.
