repo_root: String

Repository root path

actor_id: String

Actor ID (hex-encoded)

host_id: String

Stable host identifier

ipc_endpoint: String

IPC endpoint (e.g., “ipc:///tmp/grite-daemon.sock”)

Implementations

impl DaemonLock

pub fn new( pid: u32, repo_root: String, actor_id: String, host_id: String, ipc_endpoint: String, ) -> Self

Create a new daemon lock

pub fn with_lease(self, lease_ms: u64) -> Self

Create a lock with a custom lease duration

pub fn is_expired(&self) -> bool

Check if the lock has expired

pub fn is_owned_by_current_process(&self) -> bool

Check if the lock is held by this process

pub fn time_remaining_ms(&self) -> u64

Remaining time until expiration in milliseconds

pub fn refresh(&mut self)

Refresh the heartbeat and extend the lease

pub fn lock_path(data_dir: &Path) -> PathBuf

Get the lock file path for an actor data directory

pub fn read(data_dir: &Path) -> Result<Option<Self>, IpcError>

Read a lock from the filesystem

pub fn write(&self, data_dir: &Path) -> Result<(), IpcError>

Write the lock to the filesystem

pub fn remove(data_dir: &Path) -> Result<(), IpcError>

Remove the lock file

pub fn acquire( data_dir: &Path, repo_root: String, actor_id: String, host_id: String, ipc_endpoint: String, ) -> Result<Self, IpcError>

Try to acquire the lock

Returns Ok(lock) if acquired, Err if held by another non-expired process

pub fn release(data_dir: &Path) -> Result<(), IpcError>

Release the lock (only if owned by current process)
