Enum LookupError 

#[non_exhaustive]
pub enum LookupError {
    UnknownCurrency {
        code: Box<str>,
        table: RateType,
    },
    PeriodNotAvailable {
        table: RateType,
        period: Period,

Why a rate lookup failed.

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.

UnknownCurrency

The code never appears anywhere in this rate series (or is not a valid code).

Fields

code: Box<str>

table: RateType

PeriodNotAvailable

The series has no table for this period; available gives the loaded range.

Fields

table: RateType

period: Period

available: Option<(Period, Period)>

NotInPeriod

The period exists but this currency is absent from it.

Fields

currency: Currency

table: RateType

period: Period

Trait Implementations

impl Clone for LookupError

fn clone(&self) -> LookupError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LookupError

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

Formats the value using the given formatter.

impl Display for LookupError

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

Formats the value using the given formatter.

impl Eq for LookupError

impl Error for LookupError

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 LookupError

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

Equality operator ==.

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

Inequality operator !=.
