Enum ServiceError 

pub enum ServiceError {
    InvalidName(String),
    UntaggedHost,
    NoAssignedVip(String),
    Listen(String),
}

Why a VIP-service listen request was refused. Fail-closed by construction: there is no variant that yields a usable listen address without a genuine control-assigned VIP on a tagged host.

Variants

InvalidName(String)

The service name is not a valid svc:<dns-label> (Go ServiceName.Validate).

UntaggedHost

The node is not tagged, so it cannot host VIP services (Go ErrUntaggedServiceHost).

NoAssignedVip(String)

Control has not assigned this node a VIP address for the service (no service-host cap entry, or none covering this service). The node serves nothing rather than binding an arbitrary address — fail-closed.

Listen(String)

Binding the overlay listener on the resolved VIP failed (e.g. the netstack is unavailable, as in TUN transport mode, or the address is already in use). Carries a human-readable detail.

Trait Implementations

impl Clone for ServiceError

fn clone(&self) -> ServiceError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServiceError

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

Formats the value using the given formatter.

impl Display for ServiceError

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

Formats the value using the given formatter.

impl Eq for ServiceError

impl Error for ServiceError

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 PartialEq for ServiceError

fn eq(&self, other: &ServiceError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
