Enum RollbackForkFailure 

pub enum RollbackForkFailure {
    SchemaVersionRollback {
        current: u16,
        candidate: u16,
    },
    ForkMarkerPresent {
        location: RollbackForkStateLocation,
        marker: String,
    },
}

Rollback/fork refusal invariant failure.

Variants

SchemaVersionRollback

Candidate state declares a lower schema version than current state.

Fields

current: u16

candidate: u16

ForkMarkerPresent

A fork marker is present where silent continuation would be unsafe.

Fields

location: RollbackForkStateLocation

marker: String

Implementations

impl RollbackForkFailure

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

Stable invariant name for operator output and tests.

pub fn detail(&self) -> String

Human-readable failure detail.

Trait Implementations

impl Clone for RollbackForkFailure

fn clone(&self) -> RollbackForkFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RollbackForkFailure

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

Formats the value using the given formatter.

impl PartialEq for RollbackForkFailure

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