Enum IndicatorError 

pub enum IndicatorError {
    InvalidPeriod {
        name: &'static str,
        period: usize,
    },
    InvalidParameter {
        name: &'static str,
        parameter: &'static str,
        value: Decimal,
    },
}

Common configuration errors emitted by indicators.

Variants

InvalidPeriod

Returned when a period of zero is provided.

Fields

name: &'static str

Human-readable indicator name.

period: usize

User-provided period value.

InvalidParameter

Returned when a parameter must be non-negative.

Fields

name: &'static str

Human-readable indicator name.

parameter: &'static str

Name of the invalid parameter (e.g., std_multiplier).

value: Decimal

Provided parameter value.

Implementations

impl IndicatorError

pub fn invalid_period(name: &'static str, period: usize) -> Self

Helper constructor for invalid period errors.

pub fn invalid_parameter( name: &'static str, parameter: &'static str, value: Decimal, ) -> Self

Helper constructor for invalid parameter errors.

Trait Implementations

impl Debug for IndicatorError

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

Formats the value using the given formatter.

impl Display for IndicatorError

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

Formats the value using the given formatter.

impl Error for IndicatorError

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 IndicatorError

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

Equality operator ==.

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

Inequality operator !=.
