Enum EvaluationErrorCode

pub enum EvaluationErrorCode {
    ProviderNotReady,
    FlagNotFound,
    ParseError,
    TypeMismatch,
    TargetingKeyMissing,
    InvalidContext,
    General(String),
}

An enumerated error code represented idiomatically in the implementation language.

Variants

ProviderNotReady

The value was resolved before the provider was initialized.

FlagNotFound

The flag could not be found.

ParseError

An error was encountered parsing data, such as a flag configuration.

TypeMismatch

The type of the flag value does not match the expected type.

TargetingKeyMissing

The provider requires a targeting key and one was not provided in the evaluation context.

InvalidContext

The evaluation context does not meet provider requirements.

General(String)

The error was for a reason not enumerated above.

Trait Implementations

impl Clone for EvaluationErrorCode

fn clone(&self) -> EvaluationErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvaluationErrorCode

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

Formats the value using the given formatter.

impl Display for EvaluationErrorCode

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

Formats the value using the given formatter.

impl Error for EvaluationErrorCode

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 EvaluationErrorCode

fn eq(&self, other: &EvaluationErrorCode) -> 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.
