Struct hedera::Hbar

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

A quantity of hbar.

Implementations

impl Hbar

pub const ZERO: Hbar = _

A constant value of 0 ℏ.

pub const MIN: Hbar = _

The minimum allowable amount of hbar -50 Gℏ

pub const MAX: Self = _

The maximum allowable amount of hbar 50 Gℏ.

pub const fn new(amount: i64) -> Self

Create a Hbar containing amount ℏ.

Examples

let hbar = Hbar::new(52);
assert_eq!(hbar.to_string(), "52 ℏ");

pub const fn from_tinybars(tinybars: Tinybar) -> Self

Convert from tinybars to Hbar.

Examples

let hbar = Hbar::from_tinybars(250);
assert_eq!(hbar.to_string(), "250 tℏ");

pub fn from_unit<T>(amount: T, unit: HbarUnit) -> Self

where T: Into<Decimal>,

Convert from amount in unit to Hbar.

Truncates amount to the nearest tinybar if the resulting Hbar is not an integer amount of tinybar.

Panics

• if amount * unit.tinybars() would overflow a i64.

Examples

use hedera::Hbar;
use hedera::HbarUnit;
let value = Hbar::from_unit(20, HbarUnit::Millibar);
assert_eq!(value.to_string(), "0.02 ℏ");

pub const fn to_tinybars(self) -> Tinybar

Returns the value of self in Tinybars.

pub fn to(self, unit: HbarUnit) -> Decimal

Returns self as Decimal units.

pub fn get_value(self) -> Decimal

Returns self as Decimal hbars.

Examples

use rust_decimal::Decimal;
use hedera::Hbar;
let value: Hbar = "20 mℏ".parse().unwrap();

let value_decimal: Decimal = "0.02".parse().unwrap();

assert_eq!(value.get_value(), value_decimal);

pub fn negated(self) -> Self

Returns -self.
