Typed failure from static or input-dependent engine resolution.

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.

SettingsWithoutSelection

Settings were declared without selecting an engine profile.

UnknownProfile(ProfileSelection)

No exact registry tuple matches the selection.

UnknownSetting

A setting key is not in the selected profile’s descriptor inventory.

Fields

key: String

Supplied setting key.

location: SettingLocation

Declaration location.

WrongScope

A known setting was declared in the wrong scope.

Fields

setting: SettingId

Stable setting id.

expected: SettingScope

Descriptor scope.

found: SettingScope

Supplied scope.

location: SettingLocation

Declaration location.

NotApplicable

A known descriptor genuinely does not apply to the selected profile.

Fields

setting: SettingId

Stable setting id.

location: SettingLocation

Declaration location.

InvalidSettingValue

A setting value is outside its closed descriptor domain.

Fields

setting: SettingId

Stable setting id.

location: SettingLocation

Declaration location.

reason: InvalidSettingReason

Exact domain/path failure.

MissingRequiredSetting

One required-without-default setting was not materialized.

Fields

setting: SettingId

Stable setting id.

location: SettingLocation

Document or exact real clip requiring the setting.

UnacceptedInputFormat

The authoritative input container is outside the selected V1 boundary.

Fields

selection: ProfileSelection

Selected exact profile tuple.

format: SourceFormatV1

Authoritative loader-owned input format.

ResolvedSettingsContract(EngineContractError)

Fully materialized settings exceeded or contradicted the bounded V1 engine contract.

Trait Implementations

impl Clone for ResolutionError

fn clone(&self) -> ResolutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolutionError

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

Formats the value using the given formatter.

impl Display for ResolutionError

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

Formats the value using the given formatter.

impl Eq for ResolutionError

impl Error for ResolutionError

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<EngineContractError> for ResolutionError

fn from(source: EngineContractError) -> Self

Converts to this type from the input type.

impl PartialEq for ResolutionError

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

Equality operator ==.

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

Inequality operator !=.
