Enum FxError 

#[non_exhaustive]
pub enum FxError {
    MixedPairs,
    SameDirection,
    NonAscendingDates {
        near: NaiveDate,
        far: NaiveDate,
    },
    MixedCollateral,
    SettlementOutsidePair {
        settle: Currency,
    },
    SourceOutsidePair {
        source: FixingSource,
    },
}

An FX instrument that cannot be built as specified.

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.

MixedPairs

A swap’s two forwards are on different pairs.

SameDirection

A swap’s two forwards run in the same direction.

NonAscendingDates

A swap’s far value date is not after its near.

Fields

near: NaiveDate

The near leg’s value date.

far: NaiveDate

The far leg’s value date.

MixedCollateral

A swap’s two forwards discount under different collateral keys.

SettlementOutsidePair

A cash settlement currency that is neither currency of the pair.

Fields

settle: Currency

The currency named.

SourceOutsidePair

A cross fixing that does not fix this pair’s quote per base, or a settlement other than the cross’s settlement currency.

Fields

source: FixingSource

The fixing named.

Trait Implementations

impl Clone for FxError

fn clone(&self) -> FxError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FxError

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

Formats the value using the given formatter.

impl Display for FxError

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

Formats the value using the given formatter.

impl Eq for FxError

impl Error for FxError

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 FxError

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