Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Idle

No handoff in progress.

Beginning

Source region has been told to begin draining.

Fields

source_region: String

HandingOff

Entities are stopping; new messages buffer at the source.

Fields

source_region: String

remaining_entities: usize

Stopped

All entities stopped; awaiting reassignment.

Fields

source_region: String

Started

Shard re-allocated to target_region.

Fields

source_region: String

target_region: String

Trait Implementations

impl Clone for HandoffState

fn clone(&self) -> HandoffState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandoffState

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

Formats the value using the given formatter.

impl PartialEq for HandoffState

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