        from: u32,
        to: u32,
    },
    PrimaryKeyMismatch,

}

Validation or canonical-codec failure for migration protocol objects.

Variants

CollectionMismatch

The transition crossed collection identities.

NonAdjacentVersion

The target did not immediately follow its predecessor.

Fields

from: u32

to: u32

PrimaryKeyMismatch

The stable primary-key contract changed.

MixedStagingSet

Stages from different migrations or schema transitions were combined.

DuplicateSourceRecord

Two stages selected the same source primary key.

RecordIdTooLarge(usize)

A source key exceeded the protocol bound.

TargetRecordTooLarge(usize)

A target materialization exceeded the operation payload bound.

Schema(SchemaError)

A nested schema was invalid.

UnsupportedFormat

The object format major, minor, or kind is unsupported.

InvalidEncoding(String)

The binary object was malformed.

NonCanonicalEncoding

The object was valid CBOR but not its unique representation.

Trait Implementations

impl Clone for MigrationCodecError

fn clone(&self) -> MigrationCodecError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationCodecError

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

Formats the value using the given formatter.

impl Display for MigrationCodecError

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

Formats the value using the given formatter.

impl Error for MigrationCodecError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<SchemaError> for MigrationCodecError

fn from(source: SchemaError) -> Self

Converts to this type from the input type.

impl PartialEq for MigrationCodecError

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