Enum OperationalError 

#[non_exhaustive]
pub enum OperationalError {
    InvalidCatalog {
        reason: &'static str,
    },
    InvalidProviderPack {
        reason: &'static str,
    },
    InvalidLanguageIntelligenceInput {
        reason: &'static str,

    InvalidIntermediateRepresentation {
        reason: &'static str,
    },
}

Failure in execution inputs or internal pipeline invariants, not in Stack source.

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.

InvalidCatalog

A provided catalog violates an invariant required by pure execution.

Fields

reason: &'static str

Stable explanation of the violated catalog invariant.

InvalidProviderPack

A provider pack violates safe deterministic rendering invariants.

Fields

reason: &'static str

Stable explanation of the violated provider-pack invariant.

InvalidLanguageIntelligenceInput

A language-intelligence request violates its stateless input contract.

Fields

reason: &'static str

Stable explanation of the invalid source position or completion catalog.

InvalidIntermediateRepresentation

Compiler or layout data violates an invariant required by pure execution.

Fields

reason: &'static str

Stable explanation of the violated invariant.

Trait Implementations

impl Clone for OperationalError

fn clone(&self) -> OperationalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationalError

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

Formats the value using the given formatter.

impl Display for OperationalError

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

Formats the value using the given formatter.

impl Eq for OperationalError

impl Error for OperationalError

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 OperationalError

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

Equality operator ==.

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

Inequality operator !=.
