Struct CurrencyCode

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

An ISO 4217 three-letter currency code (e.g., USD).

Currency codes must be exactly 3 ASCII uppercase letters.

Implementations

impl CurrencyCode

pub fn new(code: [u8; 3]) -> Result<Self, CurrencyCodeError>

Creates a new CurrencyCode from a 3-byte array.

Returns an error if the bytes are not valid UTF-8 or not all ASCII uppercase.

pub fn as_bytes(&self) -> &[u8; 3]

Returns the currency code as a byte array.

pub fn as_str(&self) -> &str

Returns the currency code as a string slice.

Trait Implementations

impl AsRef<[u8]> for CurrencyCode

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CurrencyCode

fn clone(&self) -> CurrencyCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CurrencyCode

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

Formats the value using the given formatter.

impl Display for CurrencyCode

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

Formats the value using the given formatter.

impl FromStr for CurrencyCode

type Err = CurrencyCodeError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CurrencyCode

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 CurrencyCode

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