Struct arti::reload_cfg::FileWatcherBuilder
source · struct FileWatcherBuilder {
watching_dirs: HashSet<PathBuf>,
watching_files: HashSet<PathBuf>,
}
Expand description
Builder used to configure a FileWatcher
before it starts watching for changes.
Fields§
§watching_dirs: HashSet<PathBuf>
The list of directories that we’re currently watching.
watching_files: HashSet<PathBuf>
The list of files we actually care about.
Implementations§
source§impl FileWatcherBuilder
impl FileWatcherBuilder
sourcefn prepare<'a>(
&mut self,
sources: &'a ConfigurationSources
) -> Result<FoundConfigFiles<'a>>
fn prepare<'a>( &mut self, sources: &'a ConfigurationSources ) -> Result<FoundConfigFiles<'a>>
Find the configuration files and prepare the watcher
sourcefn watch_file<P: AsRef<Path>>(&mut self, path: P) -> Result<()>
fn watch_file<P: AsRef<Path>>(&mut self, path: P) -> Result<()>
Add a single file (not a directory) to the list of things to watch.
Idempotent: does nothing if we’re already watching that file.
sourcefn watch_dir<P: AsRef<Path>>(&mut self, path: P) -> Result<()>
fn watch_dir<P: AsRef<Path>>(&mut self, path: P) -> Result<()>
Add a directory (but not any subdirs) to the list of things to watch.
Idempotent.
sourcefn watch_just_parents(&mut self, path: &Path) -> Result<PathBuf>
fn watch_just_parents(&mut self, path: &Path) -> Result<PathBuf>
Add the parents of path
to the list of things to watch.
Returns the absolute path of path
.
Idempotent.
sourcefn watch_just_abs_dir(&mut self, watch_target: &Path)
fn watch_just_abs_dir(&mut self, watch_target: &Path)
Add just this (absolute) directory to the list of things to watch.
Does not watch any of the parents.
Idempotent.
sourcefn start_watching(self, tx: Sender<Event>) -> Result<FileWatcher>
fn start_watching(self, tx: Sender<Event>) -> Result<FileWatcher>
Build a FileWatcher
and start sending events to tx
.
For the watching to be reliably effective (race-free), the config must be read
after this point, using the FoundConfigFiles
returned by prepare
.
