Enum AnalyticsError 

pub enum AnalyticsError {
    ZeroCustomers,
    EmptyInput(String),
    ComputationError(String),
    InvalidParameter(String),
}

Error type for analytics computations.

Variants

Zero customers — cannot compute customer-weighted metrics.

EmptyInput(String)

Empty input vector where non-empty expected.

ComputationError(String)

Numerical computation error.

InvalidParameter(String)

Invalid input parameter.

Trait Implementations

impl Clone for AnalyticsError

fn clone(&self) -> AnalyticsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnalyticsError

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

Formats the value using the given formatter.

impl Display for AnalyticsError

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

Formats the value using the given formatter.

impl Error for AnalyticsError

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 AnalyticsError

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