Struct StateFile 

pub struct StateFile { /* private fields */ }

SQLite-backed persistence for daemon state and status.

Implementations

impl StateFile

pub fn new(data_dir: &Path) -> Self

Store the data directory path. The database is not opened yet — call db() to open it lazily.

pub fn save(&self, state: &DaemonState) -> Result<()>

Persist the daemon lifecycle state.

Errors

Returns an error when the database cannot be written.

pub fn load(&self) -> Result<Option<DaemonState>>

Load the daemon lifecycle state, returning None if absent.

Errors

Returns an error when the database cannot be read.

pub fn save_status(&self, report: &DaemonStatusReport) -> Result<()>

Persist the current daemon activity report.

Errors

Returns an error when the database cannot be written.

pub fn load_status(&self) -> Result<Option<DaemonStatusReport>>

Load the last daemon activity report.

Errors

Returns an error when the database cannot be read.

pub fn exists(&self) -> bool

Check whether a lifecycle row exists (equivalent to the old file check).

pub fn remove(&self) -> Result<()>

Remove the daemon lifecycle row.

Errors

Returns an error when the database operation fails.

pub fn remove_status(&self) -> Result<()>

Remove the daemon status rows.

Errors

Returns an error when the database operation fails.

pub fn is_running(&self) -> Result<bool>

Return whether the stored lifecycle indicates a still-running daemon.

Errors

Returns an error when the database cannot be read.
