Failure while validating input or replaying.

Variants

EmptyEvents

Backtest requires at least one historical event.

InvalidEventLimit

Max_events must be greater than 0.

InvalidCaptureRate

Capture_every must be greater than 0.

EventLimitExceeded

More events than max_events.

Fields

actual: usize

Events supplied.

maximum: usize

Configured max_events.

InvalidInitialValue(f64)

Initial value must be finite and greater than zero, got.

NonMonotonicTimestamp

Event timestamps are out of order at index index: previous > current.

Fields

index: usize

Index of the event being applied.

previous: i64

Timestamp of the previous event.

current: i64

Timestamp of the offending event.

Decision

The model failed to decide on an event.

Fields

index: usize

Index of the event being decided.

message: String

Model-reported failure.

Transition

State transition failed at event index, action action_index: message.

Fields

index: usize

Index of the event being applied.

action_index: usize

Index of the action within that event.

message: String

Model-reported failure.

NonFiniteValue

The model produced NaN or infinity.

Fields

index: usize

Index of the offending event.

value: f64

The non-finite value.

InvalidProjection(String)

Invalid projection policy.

Cancelled

Replay observed cancellation between events.

DeadlineExceeded

Replay exceeded its caller-provided deadline.

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 PartialEq for BacktestError

fn eq(&self, other: &BacktestError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
