Struct DaemonState 

pub struct DaemonState {
    pub pid_file: PathBuf,
    pub socket_path: PathBuf,
    pub log_file: PathBuf,
}

Manages daemon state including paths for PID file, socket, and logs.

The daemon uses files in ~/.lore/ to coordinate between the running daemon process and CLI commands that interact with it.

Fields

pid_file: PathBuf

Path to the PID file (~/.lore/daemon.pid).

socket_path: PathBuf

Path to the Unix socket (~/.lore/daemon.sock).

log_file: PathBuf

Path to the log file (~/.lore/daemon.log).

Implementations

impl DaemonState

pub fn new() -> Result<Self>

Creates a new DaemonState with default paths in ~/.lore/.

Creates the ~/.lore/ directory if it does not exist.

Errors

Returns an error if the home directory cannot be determined or if the .lore directory cannot be created.

pub fn is_running(&self) -> bool

Checks if the daemon is currently running.

Returns true if a PID file exists and the process with that PID is still alive. Returns false if no PID file exists, the PID file cannot be read, or the process is no longer running.

pub fn get_pid(&self) -> Option<u32>

Gets the PID of the running daemon, if available.

Returns None if the PID file does not exist or cannot be parsed.

pub fn write_pid(&self, pid: u32) -> Result<()>

Writes the current process ID to the PID file.

Errors

Returns an error if the PID file cannot be created or written to.

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

Removes the PID file.

Does not return an error if the file does not exist.

Errors

Returns an error if the file exists but cannot be removed.

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

Removes the Unix socket file.

Does not return an error if the file does not exist.

Errors

Returns an error if the file exists but cannot be removed.

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

Cleans up all daemon state files (PID file and socket).

Called during graceful shutdown.
