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.

InvalidSchema

A contract schema id did not match its immutable V1 value.

Fields

field: &'static str

Field carrying the invalid schema id.

expected: &'static str

Required immutable schema id.

found: String

Supplied schema id.

EmptyText

A required retained string was empty.

Fields

field: &'static str

Invalid field.

TextTooLong

One retained string exceeded the per-value byte limit.

Fields

field: &'static str

Oversized field.

found: usize

Observed UTF-8 byte count.

max: usize

Maximum permitted byte count.

TooManyRows

One collection exceeded the V1 row limit.

Fields

field: &'static str

Oversized collection.

found: usize

Observed row count.

max: usize

Maximum permitted row count.

TooManyAggregateRows

Aggregate profile/settings rows exceeded the V1 limit.

Fields

found: usize

Observed aggregate row count.

max: usize

Maximum permitted aggregate row count.

TooMuchAggregateText

Aggregate retained UTF-8 text exceeded the V1 limit.

Fields

found: usize

Observed aggregate UTF-8 byte count.

max: usize

Maximum permitted aggregate byte count.

ArithmeticOverflow

Checked arithmetic overflowed while accounting bounded work.

Fields

field: &'static str

Counter that overflowed.

DuplicateKey

A set/map-shaped collection contains a duplicate stable key.

Fields

field: &'static str

Collection containing the duplicate.

key: String

Duplicate stable key.

NonCanonicalOrder

A canonical collection is not in its required order.

Fields

field: &'static str

Unordered collection.

InvalidFactInventory

The complete closed fact-id inventory is absent or malformed.

InvalidFactValue

A known fact carries a value from another fact domain.

Fields

fact: EngineFactIdV1

Fact whose value is invalid.

InvalidAcceptedInputs

The accepted-input list is empty, duplicated, or noncanonical.

InvalidDescriptorDefault

A descriptor’s applicability and default state disagree.

Fields

setting: EngineSettingIdV1

Invalid setting descriptor.

UnknownSourceFact

A source references a fact absent from the profile.

Fields

source_id: String

Source id.

fact: EngineFactIdV1

Missing fact id.

SourceReferencesNonKnownFact

A source cites a fact whose state is not known.

Fields

source_id: String

Source id.

fact: EngineFactIdV1

Non-known fact id.

UnknownSourceSetting

A source references a descriptor absent from the profile.

Fields

source_id: String

Source id.

setting: EngineSettingIdV1

Missing setting id.

UnreferencedKnownFact

No primary source supports a known profile fact.

Fields

fact: EngineFactIdV1

Unsupported known fact.

UnreferencedSetting

No primary source supports a setting descriptor.

Fields

setting: EngineSettingIdV1

Unsupported descriptor.

InvalidSourceTransformPath

A source-transform path is malformed.

Fields

reason: &'static str

Stable explanation of the malformed path.

UnknownMaterializedSetting

A materialized setting is absent from the profile.

Fields

location: String

Stable document or clip location.

setting: EngineSettingIdV1

Unknown setting id.

WrongSettingScope

A materialized setting is declared at the wrong scope.

Fields

location: String

Stable document or clip location.

setting: EngineSettingIdV1

Wrong-scope setting id.

NonApplicableSetting

A materialized setting is not applicable to the profile.

Fields

location: String

Stable document or clip location.

setting: EngineSettingIdV1

Non-applicable setting id.

WrongSettingDomain

A materialized value does not match its descriptor domain.

Fields

location: String

Stable document or clip location.

setting: EngineSettingIdV1

Invalid setting id.

MissingRequiredSetting

A required-without-default setting is absent.

Fields

location: String

Stable document or clip location.

setting: EngineSettingIdV1

Missing setting id.

IdentityMismatch

A canonical identity does not match its semantic preimage.

Fields

contract: &'static str

Contract whose digest mismatched.
