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.

EmptyName(&'static str)

A stable name, identifier, field, or storage name was empty.

ZeroVersion(&'static str)

A declared version must be non-zero.

InvalidProgramId

A mutation program ID was not in canonical form.

PathTooDeep

An input path exceeded the portable segment limit.

Fields

segments: usize

Observed segment count.

max: usize

Supported segment ceiling.

ExpressionTooDeep

A portable expression or constant exceeded the nesting limit.

Fields

depth: usize

Observed nesting depth.

max: usize

Supported nesting ceiling.

TooManyOperations

A program declared too many operations.

Fields

count: usize

Observed operation count.

max: usize

Supported operation ceiling.

ValueTooLarge

A key, partition, or other bounded canonical value was too large.

Fields

kind: &'static str

Kind of bounded logical encoding.

len: usize

Observed encoded byte length.

max: usize

Supported byte ceiling.

DuplicateOrdinal

Two declarations used the same explicit ordinal.

Fields

kind: &'static str

Kind of ordered declaration.

ordinal: u32

Repeated ordinal.

NonContiguousOrdinal

Ordinals did not form a contiguous zero-based sequence.

Fields

kind: &'static str

Kind of ordered declaration.

expected: u32

Required next ordinal.

actual: u32

Observed ordinal.

DuplicateName

Two declarations used the same stable name.

Fields

kind: &'static str

Kind of named declaration.

name: String

Repeated name.

RequiredValueAbsent

A required expression evaluated as absent.

Fields

path: String

Stable expression or field description.

UnsetNotAllowed

unset appeared where the operation cannot represent it.

Fields

field: String

Field or expression position.

InvalidKeyValue

A key component was null, absent, unset, or structurally invalid.

Fields

field: String

Key component name.

InvalidOperation

An operation shape was incompatible with its semantic kind.

Fields

operation: String

Stable operation identifier.

reason: String

Validation reason.

AmbiguousMutation

Two operations could not deterministically become one final mutation.

Fields

model: String

Affected logical model.

reason: String

Validation reason.

InvalidReturning

Returning selection was empty or ambiguous.

Fields

reason: String

Validation reason.

InvalidConflictTarget

Conflict target was incomplete or unknown.

Fields

reason: String

Validation reason.

CanonicalJson(String)

Canonical JSON encoding failed.

MissingInput

A bound input path was missing from the supplied input object.

Fields

path: String

Missing input path.

Adapter(String)

A binding or interpreter failed while adapting to projection IR.

Trait Implementations

impl Clone for MutationProgramError

fn clone(&self) -> MutationProgramError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MutationProgramError

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

impl Eq for MutationProgramError

impl Error for MutationProgramError

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