Bootstrap-layer errors are deliberately typed so startup never panics for ordinary daemon-discovery races or stale filesystem state.

Variants

StartupNotServing

The bound server could not authenticate its own readiness probe.

Signal(Error)

InvalidPort

Fields

raw: String

source: ParseIntError

ConnectionFileRead

Fields

path: PathBuf

source: ConnectionFileError

ConnectionFileWrite

Fields

path: PathBuf

source: ConnectionFileError

GenerateConnectionFile(ConnectionFileError)

StartLockCreate

Fields

path: PathBuf

source: Error

StartLockBusy

Fields

path: PathBuf

attempts: usize

RunDirLockCreate

The run-directory lock file could not be created, opened or locked.

Fields

path: PathBuf

source: Error

RunDirBusy

Another live process, almost certainly a daemon started with a different runtime directory over the same data home, owns the run directory. The daemon does not start. holder_pid is read from the lock file when possible and is informational only.

Fields

path: PathBuf

holder_pid: Option<u32>

RemoveStale

Fields

path: PathBuf

source: Error

Bind

Fields

host: String

port: u16

source: Error

LocalAddr

Fields

host: String

source: Error

DaemonConfig(DaemonConfigError)

MachineId(MachineIdFileError)

The machine id could not be established: its file is corrupt, unreadable or unwritable, or the data home is relative. The daemon does not start.

RunDir(DaemonRunDirError)

The daemon run directory could not be resolved because the data home is relative. The daemon does not start.

Serve(ServerError)

ServeJoin(JoinError)

Trait Implementations

impl Debug for BootstrapError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BootstrapError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for BootstrapError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
