Schema-shape or schema-version invariant failure.

Variants

MissingTable

A required table is missing.

Fields

table: &'static str

MissingColumn

A required table is missing a required column.

Fields

table: &'static str

column: &'static str

UnknownMigration

The migrations table contains a migration this binary does not know.

Fields

name: String

Mismatch

A persisted row carries a different schema version than this binary.

Fields

table: &'static str

row_id: String

expected: u16

actual: u16

IllegalIntermediateShape

Schema v2 expand/backfill metadata is present but not complete enough to trust.

Fields

invariant: &'static str

detail: String

Implementations

impl SchemaVersionFailure

pub fn invariant(&self) -> String

Stable invariant name for operator output and tests.

pub fn detail(&self) -> String

Human-readable failure detail.

Trait Implementations

impl Clone for SchemaVersionFailure

fn clone(&self) -> SchemaVersionFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaVersionFailure

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

Formats the value using the given formatter.

impl PartialEq for SchemaVersionFailure

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