Control projection or authoring failure.

Only the variants this crate can actually raise are declared. A variant that no code path constructs is a promise the crate does not keep, and callers write dead match arms for it.

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.

WrongEntityType

Entity kind differs from the requested projection.

Fields

expected: &'static str

Expected IFC entity.

actual: String

Actual IFC entity.

MissingAttribute

Required positional attribute is absent or null.

Fields

entity: &'static str

Entity kind.

id: EntityId

Entity identifier.

attribute: &'static str

Attribute name.

UnknownEntity

Requested entity is absent.

Fields

id: EntityId

Missing identifier.

AuthoringInvalid

Draft value is invalid before staging.

Fields

entity: &'static str

Entity kind.

attribute: &'static str

Attribute or rule.

value: String

Rejected value.

UnsupportedEntity

The schema in use does not declare this entity.

Authoring an entity the schema omits is a caller error, not a silently-skipped attribute.

Fields

schema: String

Schema name.

entity: &'static str

Entity that is not declared.

Trait Implementations

impl Clone for ControlError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlError

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

Formats the value using the given formatter.

impl Display for ControlError

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

Formats the value using the given formatter.

impl Error for ControlError

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 ControlError

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

Equality operator ==.

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

Inequality operator !=.
