Struct Currency 

pub struct Currency(/* private fields */);

A currency by its code: three upper-case letters for an ISO 4217 currency (EUR, CHF), x- and 1–62 characters of a-z, 0-9 and - for a currency defined outside ISO 4217 (x-btc, x-galleon).

The two forms cannot collide. Only the form is checked; whether a code denotes an existing currency, and how it divides, is reference data (CurrencyDefinition), not protocol.

Implementations

impl Currency

pub fn as_str(&self) -> &str

The code as text.

pub fn is_iso(&self) -> bool

Whether this is an ISO 4217 code (three upper-case letters) rather than one beginning with x-.
