Enum Error 

pub enum Error {
    Config(String),
    Data(String),
    Brain(String),
    Internal(String),
}

Backtest-engine error type.

Variants

Config(String)

Configuration was missing a required field or had an invalid value.

Data(String)

Candle data was structurally valid but contained an unusable value — a non-finite (NaN/±inf) or negative OHLCV field. Caught at load time and at the start of crate::Backtest::run so a single bad row can’t silently poison the equity curve and metrics.

Brain(String)

The Brain returned an error while processing a candle.

Internal(String)

An invariant inside the engine was violated. These are bugs — please file an issue.

Trait Implementations

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<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
