Enum RootFinderError 

pub enum RootFinderError {
    NotConverged(u32, f64),
    NotInBracket,
    Callback(CallbackError),
}

Error returned by root-finding algorithms.

Variants

NotConverged(u32, f64)

The algorithm did not converge within the maximum number of iterations.

NotInBracket

The root is not within the given bracket.

Callback(CallbackError)

The objective function returned an error.

Trait Implementations

impl Debug for RootFinderError

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

Formats the value using the given formatter.

impl Display for RootFinderError

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

Formats the value using the given formatter.

impl Error for RootFinderError

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 From<CallbackError> for RootFinderError

fn from(source: CallbackError) -> RootFinderError

Converts to this type from the input type.
