Enum RolloutTransitionError 

pub enum RolloutTransitionError {
    IllegalForState {
        from: RolloutState,
        event: &'static str,
        rollout_id: RolloutId,
    },
    SupersessionExpected {
        rollout_id: RolloutId,
        channel: String,
    },
    Invariant(&'static str),
    Unimplemented {
        from: RolloutState,
        event: &'static str,
    },
}

Variants

IllegalForState

The event is not legal from the current RolloutState. Typically out-of-order arrival (e.g., RolloutTerminal from Opening before any host joined).

Fields

from: RolloutState

event: &'static str

rollout_id: RolloutId

SupersessionExpected

A RolloutOpened arrived for a (channel, ref) whose channel already has an active_rollout_id. The planner must emit SuccessorOpened first (RFC-0008 §3 invariant).

Fields

rollout_id: RolloutId

channel: String

Invariant(&'static str)

Invariant from RFC-0008 §3 violated by the event’s payload (e.g., RolloutTerminal while at least one host is not Converged).

Unimplemented

Reducer arm not yet implemented. Returned by the Phase 10a skeleton; every variant gets a real arm in Phase 10b. Should never be reached after Phase 10 closes — if it is, that’s a code defect.

Fields

from: RolloutState

event: &'static str

Trait Implementations

impl Clone for RolloutTransitionError

fn clone(&self) -> RolloutTransitionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RolloutTransitionError

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

Formats the value using the given formatter.

impl Display for RolloutTransitionError

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

Formats the value using the given formatter.

impl Error for RolloutTransitionError

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 RolloutTransitionError

fn eq(&self, other: &RolloutTransitionError) -> 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.
