Enum BesselError 

pub enum BesselError {
    InvalidInput,
    Overflow,
    PrecisionLoss,
    TotalPrecisionLoss,
    ConvergenceFailure,
}

Error type for Bessel function computation.

Variants

InvalidInput

Invalid input (e.g., z=0 for Hankel, negative order).

Overflow

Overflow: |z| or ν too large, or |z| too small.

PrecisionLoss

Argument reduction caused loss of more than half of significant digits.

TotalPrecisionLoss

Argument reduction caused loss of all significant digits.

ConvergenceFailure

Algorithm did not meet termination criteria.

Trait Implementations

impl Clone for BesselError

fn clone(&self) -> BesselError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BesselError

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

Formats the value using the given formatter.

impl Display for BesselError

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

Formats the value using the given formatter.

impl Error for BesselError

Available on crate feature std only.

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 BesselError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
