Trait Implementations

impl Default for GnuCash

fn default() -> GnuCash

Returns the “default value” for a type.

impl Engine for GnuCash

fn load(&mut self, setup: &Setup) -> Result<(), Refusal>

Set the books up: the chart, the fixed assets, the schedules, the parties, the members, the payees and their dated decisions, the payment methods and the projects.

fn apply(&mut self, event: &Event) -> Result<(), Refusal>

Apply one event: an entry, a reversal, a close, a bill, an invoice, a depreciation run, a disposal, a schedules run or a schedule’s registration. An event the engine refuses leaves the books as they were.

fn query(&self, q: &Query) -> Result<Value, Refusal>

Answer one query with the engine’s own figures. A figure is an exact decimal string (never a JSON number: no engine may round a cent through a float), a date is YYYY-MM-DD, and a format query’s value is its lines or rows. A query the engine refuses (a period the rule refuses, a command it refuses) is an Err.

fn claims(&self) -> Claims

The rules and choices this engine declares.

fn change(&mut self, _change: &ChangeSpec) -> Result<(), Refusal>

Apply one change that posts no entry (a [[changes]] entry).
