Enum GraphError 

pub enum GraphError {
    Render(String),
    Io(Error),
    Curve(CurveError),
    Surface(SurfaceError),
    Decimal(Box<DecimalError>),
    Backtest(Box<BacktestError>),
}

Represents errors that can occur during graph generation and rendering operations.

This error type encapsulates failures that may happen when creating, rendering, or saving graphical representations of financial data such as option chains, volatility surfaces, or strategy payoffs.

Variants

Render(String)

Represents errors that occur during the rendering process. Contains a descriptive message about what went wrong.

Io(Error)

Represents I/O errors that occur when reading from or writing to files (e.g., when saving graphs to disk).

Curve(CurveError)

Error from curve operations.

Surface(SurfaceError)

Error from surface operations.

Decimal(Box<DecimalError>)

A figure a report derives for display (a total, an average) left the representable Decimal range.

Backtest(Box<BacktestError>)

The backtest figures a report shows could not be computed, for example when the statistics of a SimulationStats accumulator overflow Decimal.

Trait Implementations

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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.
