Enum Error 

pub enum Error {
    PeriodZero,
    InvalidPeriod {
        message: &'static str,
    },

}

Errors that can occur when constructing or operating on an indicator.

Variants

PeriodZero

A period (window length) must be at least one.

InvalidPeriod

A specific minimum period requirement was not met (e.g. MACD needs slow > fast).

Fields

message: &'static str

NonFiniteInput

A non-finite value (NaN or infinity) was passed where a finite price was expected.

InvalidCandle

A candle whose components do not form a valid bar (e.g. high < low) was provided.

Fields

message: &'static str

InvalidTick

A tick whose components do not satisfy the tick invariants (e.g. negative volume) was provided. Ticks are a different concept from candles and surface as their own variant so consumers of a tick-stream pipeline can match on a semantically-correct error instead of InvalidCandle.

Fields

message: &'static str

NonPositiveMultiplier

A multiplier or factor must be strictly positive.

InvalidOrderBook

An order-book snapshot whose levels do not satisfy the book invariants (e.g. a crossed book, non-finite price, negative size, or mis-sorted levels) was provided. Order books are a microstructure input distinct from candles and ticks, so they surface as their own variant.

Fields

message: &'static str

InvalidTrade

A trade whose components do not satisfy the trade invariants (e.g. non-finite price or negative size) was provided.

Fields

message: &'static str

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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