Enum MigrationPhase 

pub enum MigrationPhase {
    Settled,
    Draining,
    Cutover,
}

The partition’s migration phase at read time, a shape-only label (never tenant data) so observability can show where a migration is (docs/06 §5).

Examples

use osproxy_spi::MigrationPhase;
assert_eq!(MigrationPhase::default(), MigrationPhase::Settled);
assert_eq!(MigrationPhase::Cutover.as_str(), "cutover");

Variants

Settled

Not migrating; the placement is settled.

Draining

Migrating, copy phase, writes still go to the origin.

Cutover

Migrating, cutover window, writes are held (stale-epoch retry).

Implementations

impl MigrationPhase

pub fn as_str(self) -> &'static str

A stable lowercase label for telemetry.

Trait Implementations

impl Clone for MigrationPhase

fn clone(&self) -> MigrationPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MigrationPhase

impl Debug for MigrationPhase

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

Formats the value using the given formatter.

impl Default for MigrationPhase

fn default() -> MigrationPhase

Returns the “default value” for a type.

impl Eq for MigrationPhase

impl PartialEq for MigrationPhase

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