Enum MarketDataError 

#[non_exhaustive]
pub enum MarketDataError {
    MissingFixing {
        index: Box<str>,
        date: NaiveDate,
    },
    MissingFxRate {
        pair: Box<str>,
    },
    ParameterCountMismatch {
        expected: usize,
        given: usize,
    },
    Malformed(&'static str),
    UnknownFixingIndex(Box<UnknownFixingIndexError>),
}

A market-data lookup that cannot be answered.

Distinct from a curve error: this is about a value that was never supplied, not a query a curve could not answer. Both are typed, and neither is a panic.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingFixing

No fixing was published for this index on this date.

The name is a Box<str> rather than a String: it is never grown, and the narrower field keeps this enum — and every Result carrying it through a coupon projection — at 24 bytes.

Fields

index: Box<str>

The index asked for.

date: NaiveDate

The date asked for.

MissingFxRate

No FX rate was supplied for this pair.

Fields

pair: Box<str>

The pair asked for, as BASE/QUOTE.

ParameterCountMismatch

A substituted lift was handed a parameter vector of the wrong length.

Fields

expected: usize

How many free parameters the store has.

given: usize

How many were supplied.

Malformed(&'static str)

The store was built with contradictory or malformed entries.

UnknownFixingIndex(Box<UnknownFixingIndexError>)

An observation was published under a spelling that keys nothing: not a registered index code in its registered casing, and not a well-formed FX key. Boxed for the same reason MissingFixing narrows its field — the enum, and every Result carrying it, stays at 24 bytes.

Implementations

impl MarketDataError

pub fn missing_input(&self) -> Option<(&'static str, String)>

The value this lookup found missing, as the (kind, key) row MarketContext::contents lists once it is supplied: ("fixing", "INDEX@DATE") or ("fx", "BASE/QUOTE"). None for a refusal that is not a missing value. Exhaustive, so a new variant does not compile until someone decides.

Trait Implementations

impl Clone for MarketDataError

fn clone(&self) -> MarketDataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MarketDataError

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

Formats the value using the given formatter.

impl Display for MarketDataError

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

Formats the value using the given formatter.

impl Eq for MarketDataError

impl Error for MarketDataError

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<FxVolError> for MarketDataError

fn from(e: FxVolError) -> Self

Converts to this type from the input type.

impl From<MarketDataError> for CashflowError

fn from(e: MarketDataError) -> Self

Converts to this type from the input type.

impl From<MarketDataError> for PricingError

fn from(e: MarketDataError) -> Self

Converts to this type from the input type.

impl From<RateVolError> for MarketDataError

fn from(e: RateVolError) -> Self

Converts to this type from the input type.

impl PartialEq for MarketDataError

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