Enum IndicatorError 

pub enum IndicatorError {
    InsufficientData {
        required: usize,
        actual: usize,
    },
    InvalidParameter(String),
    Calculation(String),
    NotInitialized(String),
    InvalidPrice(String),
    InvalidInput(String),
    DivisionByZero,
}

Errors that can occur during indicator calculations.

Variants

InsufficientData

Insufficient data to calculate the indicator.

Most indicators require a minimum number of data points (warmup period) before they can produce valid output.

Fields

required: usize

Minimum required data points

actual: usize

Actual number of data points available

InvalidParameter(String)

Invalid parameter provided to indicator constructor.

For example, a period of 0 or a negative standard deviation.

Calculation(String)

Error during calculation.

This can occur due to numerical issues like division by zero, overflow, or invalid mathematical operations.

NotInitialized(String)

Indicator not properly initialized.

This error occurs when trying to use an indicator before it’s ready.

InvalidPrice(String)

Invalid price data.

Prices cannot be negative or NaN.

InvalidInput(String)

Invalid input data.

General validation error for input data.

DivisionByZero

Division by zero encountered.

Trait Implementations

impl Clone for IndicatorError

fn clone(&self) -> IndicatorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndicatorError

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

Formats the value using the given formatter.

impl Display for IndicatorError

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

Formats the value using the given formatter.

impl Error for IndicatorError

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 IndicatorError

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