Struct inotify::EventMask

pub struct EventMask { /* private fields */ }

Indicates the type of an event

This struct can be retrieved from an Event via its mask field. You can determine the Event’s type by comparing the EventMask to its associated constants.

Please refer to the documentation of Event for a usage example.

Implementations

impl EventMask

pub const ACCESS: Self = _

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.

pub const ATTRIB: Self = _

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.

pub const CLOSE_WRITE: Self = _

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.

pub const CLOSE_NOWRITE: Self = _

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.

pub const CREATE: Self = _

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.

pub const DELETE: Self = _

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.

pub const DELETE_SELF: Self = _

Watched file/directory was deleted

See inotify_sys::IN_DELETE_SELF.

pub const MODIFY: Self = _

File was modified

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

See inotify_sys::IN_MODIFY.

pub const MOVE_SELF: Self = _

Watched file/directory was moved

See inotify_sys::IN_MOVE_SELF.

pub const MOVED_FROM: Self = _

File was renamed/moved; watched directory contained old name

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

See inotify_sys::IN_MOVED_FROM.

pub const MOVED_TO: Self = _

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.

pub const OPEN: Self = _

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.

pub const IGNORED: Self = _

Watch was removed

This event will be generated, if the watch was removed explicitly (via [Watches::remove]), or automatically (because the file was deleted or the file system was unmounted).

See inotify_sys::IN_IGNORED.

pub const ISDIR: Self = _

Event related to a directory

The subject of the event is a directory.

See inotify_sys::IN_ISDIR.

pub const Q_OVERFLOW: Self = _

Event queue overflowed

The event queue has overflowed and events have presumably been lost.

See inotify_sys::IN_Q_OVERFLOW.

pub const UNMOUNT: Self = _

File system containing watched object was unmounted. File system was unmounted

The file system that contained the watched object has been unmounted. An event with WatchMask::IGNORED will subsequently be generated for the same watch descriptor.

See inotify_sys::IN_UNMOUNT.

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u32) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Self) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Self, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
