Enum EvalError

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

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.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl PartialEq for Error

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

impl Serialize for Error

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
