Enum DiffError

pub enum DiffError {
    CalcError(CalcError),
    Boxed(Box<dyn Error + Send + Sync>),
    DerivativeNotFound,
    UnknownError,
}

Variants

CalcError(CalcError)

A function has had an error covered by CalcError

Mostly used for invalid arguments count

Boxed(Box<dyn Error + Send + Sync>)

A user-defined error

Is used when implementing custom function with differentiation logic

DerivativeNotFound

A function was encountered and it wasn’t registered as differentiable

UnknownError

Unknown error encountered

Trait Implementations

impl Debug for DiffError

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

Formats the value using the given formatter.

impl Display for DiffError

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

Formats the value using the given formatter.

impl Error for DiffError

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.
