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.

EmptyIdentifier

A caller supplied an empty identifier.

Fields

field: &'static str

Field name.

TenantIdTooLong

A tenant identifier exceeded the storage contract’s byte limit.

Fields

max: usize

Maximum permitted UTF-8 byte length.

actual: usize

Supplied UTF-8 byte length.

TenantIdControlCharacter

A tenant identifier contained a Unicode control character.

Fields

code_point: u32

Unicode scalar value of the rejected character.

TenantIdNoncharacter

A tenant identifier contained a Unicode noncharacter.

Fields

code_point: u32

Unicode scalar value of the rejected character.

TenantMismatch

Two values from different tenants were combined.

Fields

expected: TenantId

Tenant required by the owning scope.

actual: TenantId

Tenant carried by the value being checked.

InvalidFulfillmentThreshold

A fulfillment policy cannot be satisfied because its threshold is invalid.

RelationDisabled

A command targets a disabled relation.

Fields

relation_id: Uuid

Disabled relation id.

DuplicateActiveKeepsake

A caller tried to apply a relation that is already active for a subject.

Fields

subject_kind: String

Subject kind.

subject_id: String

Subject id.

relation_id: Uuid

Relation id.

InvalidKeepsakeLifecycle

A flat keepsake record did not satisfy lifecycle invariants.

Fields

reason: &'static str

Validation failure reason.

ActiveRelationMismatch

An active relation paired a keepsake with the wrong relation definition.

Fields

keepsake_relation_id: Uuid

Relation id stored on the keepsake.

relation_id: Uuid

Relation id stored on the relation definition.

InactiveActiveRelation

An active relation was built from a non-active keepsake.

Fields

keepsake_id: Uuid

Keepsake id.

Trait Implementations

impl Clone for KeepsakeError

fn clone(&self) -> KeepsakeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeepsakeError

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

Formats the value using the given formatter.

impl Display for KeepsakeError

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

Formats the value using the given formatter.

impl Eq for KeepsakeError

impl Error for KeepsakeError

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 PartialEq for KeepsakeError

fn eq(&self, other: &KeepsakeError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
