Struct FileWatcher 

pub struct FileWatcher { /* private fields */ }

Simple file change detector using modification timestamps.

Avoids the notify crate dependency by comparing cached mtimes on each poll call. Only watches files that have been explicitly registered.

Implementations

pub fn new(root: PathBuf, patterns: Vec<String>) -> Self

Create a new file watcher for the given root and patterns.

pub fn poll_changes(&mut self) -> Vec<PathBuf>

Scan watched files for mtime changes since last check. Returns paths of files that changed or were deleted.

pub fn watch(&mut self, path: PathBuf)

Register a single file to watch.

pub fn watch_directory(&mut self)

Register all files matching patterns in the root directory (non-recursive).

pub fn watched_count(&self) -> usize

Number of watched files.

pub fn is_enabled(&self) -> bool

Whether file watching is enabled.

pub fn set_enabled(&mut self, enabled: bool)
