Errors while compiling untrusted declarations into a trusted execution plan.

Variants

UnsupportedSchemaVersion

A package declares a schema version this compiler does not implement.

Fields

package_kind: &'static str

package_id: String

version: String

supported: &'static str

DuplicateDefinitionPackage(String)

Multiple supplied definition packages declared the same package identity.

UnknownCapability(String)

A capability was not registered by the host.

DuplicateCapability(String)

Two trusted implementations claimed an ID.

UnknownParameter

A package supplied a non-declared parameter.

Fields

capability: String

parameter: String

MissingParameter

A required parameter was absent.

Fields

capability: String

parameter: String

InvalidParameterType

A binding type did not conform to its descriptor.

Fields

capability: String

parameter: String

DuplicateBinding(String)

A rule binds a parameter more than once.

InvalidRuleId(String)

A rule ID violates the engine identity contract.

UnknownDefinition(String)

A rule references no loaded definition.

MissingDefinitionPackage(String)

A ruleset references a definition package that was not supplied.

CapabilityContract

A trusted capability descriptor conflicts with its portable definition.

Fields

definition: String

capability: String

detail: String

DuplicateRule(String)

Rule IDs must be unique throughout the recursive folder tree.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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 EngineError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
