Enum MetricsError 

pub enum MetricsError {
    InsufficientData {
        required: usize,
        actual: usize,
    },
    DivisionByZero {
        context: &'static str,
    },
    InvalidParameter(String),
}

Errors that can occur during metrics calculations.

Variants

InsufficientData

Not enough data points for the calculation.

Fields

required: usize

actual: usize

DivisionByZero

Division by zero would occur.

Fields

context: &'static str

InvalidParameter(String)

Invalid parameter value.

Trait Implementations

impl Debug for MetricsError

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

Formats the value using the given formatter.

impl Display for MetricsError

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

Formats the value using the given formatter.

impl Error for MetricsError

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 MetricsError

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