pub struct FileWatcher { /* private fields */ }Expand description
Cross-platform file system watcher
Uses OS-level APIs for efficient real-time file monitoring:
- Linux: inotify
- macOS:
FSEvents - Windows:
ReadDirectoryChangesW
Implementations§
Source§impl FileWatcher
impl FileWatcher
Sourcepub fn poll_changes(&self) -> Vec<FileChange>
pub fn poll_changes(&self) -> Vec<FileChange>
Poll for file changes (non-blocking)
Returns all pending file system events without blocking. Use this for periodic polling in a loop.
§Returns
Vector of file changes (empty if no changes)
Sourcepub fn wait_for_change(&self) -> Result<Vec<FileChange>>
pub fn wait_for_change(&self) -> Result<Vec<FileChange>>
Sourcepub fn wait_with_debounce(
&self,
debounce_duration: Duration,
) -> Result<Vec<FileChange>>
pub fn wait_with_debounce( &self, debounce_duration: Duration, ) -> Result<Vec<FileChange>>
Wait for next file change with debouncing
Waits for a file system event, then waits for debounce_duration
to collect any additional rapid-fire events (e.g., from editor saves).
This is useful for editors that save files multiple times in quick succession.
§Arguments
debounce_duration- How long to wait for additional events (typically 100-500ms)
§Returns
Vector of deduplicated file changes
§Errors
Returns anyhow::Error when the underlying watcher channel disconnects or emits an
unrecoverable error while collecting events.
Sourcepub fn wait_until(&self, duration: Duration) -> Vec<FileChange>
pub fn wait_until(&self, duration: Duration) -> Vec<FileChange>
Wait for a duration while continuously draining events from the channel
Unlike std::thread::sleep(), this actively drains the event channel,
collecting all events that arrive during the wait period. This is crucial
for macOS FSEvents which may deliver batched notifications.
Returns all file changes collected during the wait period.
