Errors returned by the encoding functions and by MicrostructuralFeaturesGenerator.

Variants

UnknownTickRule(i32)

encode_tick_rule_array received a value other than 1, -1 or 0.

NumLettersOutOfRange

quantile_mapping was asked for zero letters or more than 256.

EmptyArray

quantile_mapping or sigma_mapping received an empty array.

NanInArray

quantile_mapping, sigma_mapping or encode_array received a NaN value.

NonPositiveStep

sigma_mapping received a step that is not a positive finite number (zero, negative, NaN or infinite).

InvalidCodebook(&'static str)

encode_array or MicrostructuralFeaturesGenerator::new_from_csv received a codebook that is empty or has a NaN value, so some value would have no letter.

DictionaryTooLong

sigma_mapping would need more than 256 letters.

WrongColumnCount

The first data row of the trades CSV does not have exactly three columns.

PriceNotFloat

The price in the first data row of the trades CSV is not a number.

VolumeNotNumeric

The volume in the first data row of the trades CSV is not a number.

TimestampNotDatetime

The timestamp in the first data row of the trades CSV is not in a supported format.

ShortRow(usize)

A trades CSV row has fewer than three columns; the payload is the column count.

Csv(String)

Reading or parsing the trades CSV failed; the payload is the underlying error.

Input(InputError)

A feature function rejected its inputs.

Trait Implementations

impl Clone for MicrostructuralError

fn clone(&self) -> MicrostructuralError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MicrostructuralError

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

Formats the value using the given formatter.

impl Display for MicrostructuralError

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

Formats the value using the given formatter.

impl Error for MicrostructuralError

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 From<InputError> for MicrostructuralError

fn from(source: InputError) -> Self

Converts to this type from the input type.

impl PartialEq for MicrostructuralError

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