Enum DrawdownError 

pub enum DrawdownError {
    NonFinite,
    Positive,
    InvalidPeak,
    NegativeValue,
    EmptySeries,
    ZeroWindow,
    EmptyLabel,
}

Errors returned by drawdown helpers.

Variants

NonFinite

Drawdown and series values must be finite.

Positive

Drawdowns use zero-or-negative convention.

InvalidPeak

Peak values must be finite and strictly positive.

NegativeValue

Current values must not be negative.

EmptySeries

Maximum drawdown requires at least one value.

ZeroWindow

Window lengths must be non-zero.

EmptyLabel

Labels must be non-empty after trimming whitespace.

Trait Implementations

impl Clone for DrawdownError

fn clone(&self) -> DrawdownError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawdownError

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

Formats the value using the given formatter.

impl Display for DrawdownError

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

Formats the value using the given formatter.

impl Error for DrawdownError

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 DrawdownError

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