    Shutdown(String),
    ShutdownTimeout(Duration),
    HealthCheck(String),
    ResourceLimit {

}

Comprehensive error type for daemon operations.

Following Iron Lotus principle of explicit error handling, this enum covers all failure modes without panics.

Variants

Config(String)

Configuration error during daemon initialization.

Init(String)

Initialization failed.

Runtime(String)

Runtime error during daemon execution.

Shutdown(String)

Shutdown error.

ShutdownTimeout(Duration)

Shutdown timed out.

HealthCheck(String)

Health check failed.

ResourceLimit

Resource limit exceeded.

Fields

resource: String

The resource that was exceeded.

limit: u64

The configured limit.

actual: u64

The actual value.

PolicyViolation(String)

Policy violation.

Signal(String)

Signal handling error.

NotFound(String)

Daemon not found.

State(String)

Invalid state for operation.

Io(Error)

I/O error.

Serialization(String)

Serialization error.

Internal(String)

Internal error (should not occur in production).

Implementations

impl DaemonError

pub fn config(msg: impl Into<String>) -> Self

Creates a configuration error.

pub fn init(msg: impl Into<String>) -> Self

Creates an initialization error.

pub fn runtime(msg: impl Into<String>) -> Self

Creates a runtime error.

pub fn shutdown(msg: impl Into<String>) -> Self

Creates a shutdown error.

pub fn health_check(msg: impl Into<String>) -> Self

Creates a health check error.

pub fn policy_violation(msg: impl Into<String>) -> Self

Creates a policy violation error.

pub const fn is_recoverable(&self) -> bool

Returns true if this error is recoverable (daemon can continue).

pub const fn is_fatal(&self) -> bool

Returns true if this error requires immediate shutdown.

Trait Implementations

impl Debug for DaemonError

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

Formats the value using the given formatter.

impl Display for DaemonError

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

Formats the value using the given formatter.

impl Error for DaemonError

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.

impl From<Error> for DaemonError

fn from(source: Error) -> Self

Converts to this type from the input type.
