Enum VolatilityError 

pub enum VolatilityError {
    NonFinite,
    Negative,
    InsufficientReturns,
    TooManyReturns,
    ZeroWindow,
}

Errors returned by volatility helpers.

Variants

NonFinite

Volatility and return inputs must be finite.

Negative

Volatility must not be negative.

InsufficientReturns

Sample volatility requires at least two return observations.

TooManyReturns

Sample volatility only supports observation counts representable as u32.

ZeroWindow

Window lengths must be non-zero.

Trait Implementations

impl Clone for VolatilityError

fn clone(&self) -> VolatilityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VolatilityError

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

Formats the value using the given formatter.

impl Display for VolatilityError

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

Formats the value using the given formatter.

impl Error for VolatilityError

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 VolatilityError

fn eq(&self, other: &VolatilityError) -> 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.
