Enum BacktestError 

#[non_exhaustive]
pub enum BacktestError {
    InvalidParameter {
        param: String,
        reason: String,
    },
    InsufficientData {
        need: usize,
        got: usize,
    },

}

Backtest-specific errors

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidParameter

Invalid configuration parameter

Fields

param: String

Parameter name

reason: String

Reason for invalidity

InsufficientData

Insufficient data for backtest

Fields

need: usize

Minimum required candles

got: usize

Actual candles provided

StrategyError(String)

Strategy error during execution

IndicatorError(IndicatorError)

Indicator calculation failed

ChartError(String)

Chart data fetch failed

PositionError(String)

Position management error

Implementations

Create an invalid parameter error

pub fn insufficient_data(need: usize, got: usize) -> Self

Create an insufficient data error

pub fn strategy(msg: impl Into<String>) -> Self

Create a strategy error

pub fn chart(msg: impl Into<String>) -> Self

Create a chart error

pub fn position(msg: impl Into<String>) -> Self

Create a position error

Trait Implementations

impl Debug for BacktestError

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

Formats the value using the given formatter.

impl Display for BacktestError

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

Formats the value using the given formatter.

impl Error for BacktestError

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 From<IndicatorError> for BacktestError

fn from(source: IndicatorError) -> Self

Converts to this type from the input type.
