Enum InitializationError 

pub enum InitializationError {
    Failed {
        source: GenericError,
    },
    PermanentlyUnavailable,
}

Initialization errors.

Initialization errors are distinct from runtime errors: they indicate that a process could not be started at all (e.g., failed to bind a port, missing configuration). These errors do NOT trigger restart logic; instead, they immediately propagate up and fail the supervisor.

Variants

Failed

The process could not be initialized due to an error.

Fields

source: GenericError

The underlying error that caused initialization to fail.

PermanentlyUnavailable

The process is permanently unavailable and cannot be initialized.

This is for cases where initialization is structurally impossible, not due to a transient error.

Trait Implementations

impl Debug for InitializationError

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

Formats the value using the given formatter.

impl Display for InitializationError

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

Formats the value using the given formatter.

impl Error for InitializationError

where Self: Debug + Display,

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

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

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.

impl ErrorCompat for InitializationError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
