Struct CurrencyPair 

pub struct CurrencyPair {
    pub from_currency: String,
    pub to_currency: String,
}

Currency pair representing source and target currencies.

Fields

from_currency: String

Source (from) currency code (ISO 4217).

to_currency: String

Target (to) currency code (ISO 4217).

Implementations

impl CurrencyPair

pub fn new(from: &str, to: &str) -> Self

Creates a new currency pair.

pub fn inverse(&self) -> Self

Returns the inverse currency pair.

pub fn as_string(&self) -> String

Returns the pair as a string (e.g., “EUR/USD”).

pub fn is_same_currency(&self) -> bool

Returns true if this is a same-currency pair.

Trait Implementations

impl Clone for CurrencyPair

fn clone(&self) -> CurrencyPair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CurrencyPair

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

Formats the value using the given formatter.

impl Display for CurrencyPair

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

Formats the value using the given formatter.

impl Hash for CurrencyPair

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CurrencyPair

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