Struct CurrencyCode 

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

ISO 4217 three-letter currency code.

Stored as 3 ASCII uppercase bytes for zero-allocation comparisons and copies.

Example

use stateset_primitives::CurrencyCode;

let usd = CurrencyCode::USD;
assert_eq!(usd.as_str(), "USD");

let parsed: CurrencyCode = "EUR".parse().unwrap();
assert_eq!(parsed, CurrencyCode::EUR);
