Enum GroupError 

pub enum GroupError {
    NotReady,
    FactoryNotFound(String),
    Core(GroupError),
    Daemon(DaemonError),
}

Errors returned by the SDK’s group wrappers.

Variants

NotReady

The caller’s DaemonRuntime has not yet reached Ready. Start the runtime before constructing any group.

FactoryNotFound(String)

The caller referenced a kind that was never registered via DaemonRuntime::register_factory. Register the kind before spawning a group of that kind.

Core(GroupError)

Pass-through for errors surfaced by the core group layer (NoHealthyMember, PlacementFailed, RegistryFailed, InvalidConfig).

Daemon(DaemonError)

Pass-through for daemon-level errors surfaced during member spawn (registry collision, host construction).

Trait Implementations

impl Debug for GroupError

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

Formats the value using the given formatter.

impl Display for GroupError

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

Formats the value using the given formatter.

impl Error for GroupError

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<GroupError> for GroupError
