Struct Prefix 

pub struct Prefix<'a> { /* private fields */ }

Implements Display with the currency symbol at the front.

Methods from Deref<Target = Currency>

pub fn postfix(&self) -> Postfix<'_>

Returns an object that implements Display for different methods of printing currency.

pub fn as_float(&self) -> f64

Returns the value as float

Warning, do not use this for calculation, this is for displaying only!

pub fn value(&self) -> i64

Returns the inner value

pub fn symbol(&self) -> Option<Symbol>

Returns the inner symbol

Methods from Deref<Target = i64>

pub const MIN: i64 = -9_223_372_036_854_775_808i64

pub const MAX: i64 = 9_223_372_036_854_775_807i64

pub const BITS: u32 = 64u32

Trait Implementations

impl<'a> Deref for Prefix<'a>

type Target = Currency

The resulting type after dereferencing.

fn deref(&self) -> &Currency

Dereferences the value.

impl<'a> Display for Prefix<'a>

Allows Currencies to be displayed as Strings. The format includes no comma delimiting with a two digit precision decimal.

Examples

use claude::Currency;

assert!(Currency{ symbol: Some('$'), value: 1210}.prefix().to_string() == "$12.10");
assert!(Currency{ symbol: None, value: 1210}.prefix().to_string() == "12.10");

println!("{}", Currency{ symbol: Some('$'), value: 100099}.prefix());

The last line prints the following:

"$1000.99"

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

Formats the value using the given formatter.
