Enum BacktestError 

#[non_exhaustive]
pub enum BacktestError {
    InvalidSpec(String),
    UnknownIndicator(String),
    InvalidParams {
        indicator: String,
        reason: String,
    },
    UndeclaredRef(String),
    InvalidData(String),
}

An error raised while parsing a strategy spec or running a backtest.

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.

InvalidSpec(String)

The strategy spec could not be parsed or was structurally invalid.

UnknownIndicator(String)

An indicator referenced in the spec is unknown to the registry.

InvalidParams

An indicator was constructed with the wrong number or value of parameters.

Fields

indicator: String

The indicator type name.

reason: String

Why the parameters were rejected.

UndeclaredRef(String)

A rule referenced an indicator name that is not declared in indicators.

InvalidData(String)

The input data was empty or malformed.

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.
