Struct DrainOutcome 

pub struct DrainOutcome {
    pub member: NodeIdentity,
    pub handoffs: Vec<Result<TransitionOutcome, TransitionError>>,
    pub evacuations: Vec<ReplicaEvacuation>,
    pub blocked: Vec<DrainBlock>,
}

The outcome of running a drain: the result of each scheduled step (a hand-off outcome or an evacuation), and the ranges that stayed blocked. The membership catalog is untouched — removal is the separate, gated commit_drain_removal step.

Fields

member: NodeIdentity

handoffs: Vec<Result<TransitionOutcome, TransitionError>>

Each owned-range hand-off’s transition result, in plan order.

evacuations: Vec<ReplicaEvacuation>

Each replica evacuation that was applied, in plan order.

blocked: Vec<DrainBlock>

Ranges that could not be scheduled and still block the drain.

Implementations

impl DrainOutcome

pub fn is_drained(&self) -> bool

Did every scheduled step apply cleanly and nothing stay blocked? When true, the member now owns and replicates nothing and commit_drain_removal will succeed.

Trait Implementations

impl Clone for DrainOutcome

fn clone(&self) -> DrainOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrainOutcome

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

Formats the value using the given formatter.

impl Eq for DrainOutcome

impl PartialEq for DrainOutcome

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