pub enum EvalError {
    ClientNotReady,
    FlagNotFound,
    MalformedFlag,
    WrongType,
    Exception,
}
Expand description

Error is returned via a Reason::Error when the client could not evaluate a flag, and provides information about why the flag could not be evaluated.

Variants§

§

ClientNotReady

ClientNotReady indicates that the caller tried to evaluate a flag before the client had successfully initialized.

§

FlagNotFound

FlagNotFound indicates that the caller provided a flag key that did not match any known flag.

§

MalformedFlag

MalformedFlag indicates that there was an internal inconsistency in the flag data, e.g. a rule specified a nonexistent variation.

§

WrongType

WrongType indicates that the result value was not of the requested type, e.g. you called BoolVariationDetail but the value was an integer.

§

Exception

Exception indicates that an unexpected error stopped flag evaluation; check the log for details.
