Enum WatchEvent 

pub enum WatchEvent {
    Create,
    Delete,
    Update,
    Initial,
    DebugWatch,
}

Type of file system event.

These events correspond to inotify events, but are simplified into three categories that cover most use cases.

Variants

Create

File or directory was created.

Also triggered when a file/directory is moved into a watched directory.

Delete

File or directory was deleted.

Also triggered when a file/directory is moved out of a watched directory.

Update

File content was modified.

Triggered on IN_MODIFY (content changed) or IN_CLOSE_WRITE (file opened for writing was closed). Directory content changes (files added/removed) are reported as Create/Delete instead.

Initial

Initial event for preexisting files/directories.

Only emitted when Watcher::watch_initial is enabled. Fired once for each file or directory that matches the patterns at the time the watcher starts, before any file system events are processed.

DebugWatch

Debug event: a watch was added on this directory.

Only emitted when Watcher::debug_watches is enabled. Useful for understanding which directories are being watched based on your patterns.

Trait Implementations

impl Clone for WatchEvent

fn clone(&self) -> WatchEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for WatchEvent

impl Debug for WatchEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for WatchEvent

impl PartialEq for WatchEvent

fn eq(&self, other: &WatchEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
