Enum RouterError 

pub enum RouterError<M, O, E> {
    NoEligibleRecipients(M),
    InvalidSelection {
        message: M,
        index: usize,
        members: usize,
    },
    Policy {
        observation: O,
        error: E,
    },
}

A routing rejection that preserves the unaccepted payload.

Selection failure is ordinary typed behavior failure; it does not stop the actor, mutate policy state, or ask the runtime to fabricate a recipient.

Variants

NoEligibleRecipients(M)

No recipient was eligible at the instant this command was folded.

InvalidSelection

The selected policy returned an index outside the exact membership snapshot it received. The command and policy state remain unconsumed.

Fields

message: M

Unaccepted destination command.

index: usize

Invalid index returned by the policy.

members: usize

Size of the membership snapshot supplied to the policy.

Policy

The concrete policy rejected its typed observation atomically.

Fields

observation: O

Exact observation rejected by the policy.

error: E

Concrete policy reason.

Trait Implementations

impl<M: Clone, O: Clone, E: Clone> Clone for RouterError<M, O, E>

fn clone(&self) -> RouterError<M, O, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug, O, E: Debug> Debug for RouterError<M, O, E>

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

Formats the value using the given formatter.

impl<M, O, E> Display for RouterError<M, O, E>

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

Formats the value using the given formatter.

impl<M, O, E> Error for RouterError<M, O, E>

where Self: Debug + Display,

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<M: PartialEq, O: PartialEq, E: PartialEq> PartialEq for RouterError<M, O, E>

fn eq(&self, other: &RouterError<M, O, E>) -> 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.
