Struct ConfigWatcher 

pub struct ConfigWatcher { /* private fields */ }

Watches the config file and broadcasts validated changes — the corner team that keeps the fighter’s strategy sharp without stopping the bout.

Implementations

impl ConfigWatcher

pub fn new(config_path: PathBuf, initial_config: PunchConfig) -> Self

Create a new ConfigWatcher ready to observe the corner team’s playbook.

pub fn subscribe(&self) -> Receiver<PunchConfig>

Subscribe to config changes — get a ringside seat for every strategy adjustment.

pub fn current(&self) -> PunchConfig

Get a snapshot of the current config — check what game plan the fighter is using right now.

pub async fn start_watching(&self) -> PunchResult<()>

Start watching the config file for changes — the corner team takes their position.

Spawns a background task that monitors the config file using filesystem events and applies validated changes automatically.

pub fn apply_change( &self, new_config: PunchConfig, ) -> Result<ConfigChangeSet, ConfigValidationError>

Validate and apply a new config programmatically — a direct corner team call.

Returns the set of changes if the config is valid, or a validation error if the new config fails checks.
