Struct Balance

#[non_exhaustive]
pub struct Balance<D> {
    pub account: Account,
    pub amount: Amount<D>,
    pub tolerance: Option<D>,
}

Balance assertion

Example

use beancount_parser::{BeancountFile, DirectiveContent};
let input = "2022-05-24 balance Assets:Bank:Checking 10 CHF";
let beancount: BeancountFile<f64> = input.parse().unwrap();
let DirectiveContent::Balance(balance) = &beancount.directives[0].content else { unreachable!() };
assert_eq!(balance.account.as_str(), "Assets:Bank:Checking");
assert_eq!(balance.amount.value, 10.0);
assert_eq!(balance.amount.currency.as_str(), "CHF");

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

account: Account

Account being asserted

amount: Amount<D>

Amount the amount should have on the date

tolerance: Option<D>

Explicit precision tolerance

Trait Implementations

impl<D: Clone> Clone for Balance<D>

fn clone(&self) -> Balance<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for Balance<D>

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

Formats the value using the given formatter.

impl<D: PartialEq> PartialEq for Balance<D>

fn eq(&self, other: &Balance<D>) -> 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.
