Struct ConfigWatcher 

pub struct ConfigWatcher { /* private fields */ }

Notices when the configuration file changes, so a running rigtop can apply the edits without a restart.

Implementations

impl ConfigWatcher

pub fn new(path: PathBuf) -> Self

Watches path, taking its current state as already loaded.

pub fn path(&self) -> &Path

The file being watched.

pub fn poll(&mut self) -> Option<Result<Config, ConfigError>>

When the file changed since the previous call, its new contents (or why they cannot be used, e.g. a file saved half-way). None when unchanged, checked less than a second ago, or removed: a missing file keeps the configuration in use rather than resetting it.
