Implementations

impl Bank

pub fn change<R>( root: &Path, change: impl FnOnce(&mut Bank) -> R, ) -> Result<R, String>

Read, changed by change and written back, all under the file’s lock, which the sharing takes too: a change is set over the file as it is then, never over a copy read earlier. Returns what change returns.

pub fn load(root: &Path) -> Result<Bank, String>

pub fn import(&mut self, statement: &Statement, title: &str) -> Imported

A statement taken in: new movements added (by id), the balance kept when newer.

pub fn save(&self) -> Result<(), String>

Written whole, under the file’s lock, which the sharing takes too.

fn write(&self) -> Result<(), String>

pub fn balance_in(&self, ledger: &Ledger) -> Option<(Date, Money)>

The balance of every account together, and the newest day among them, each account once: the names a card gives one account (its number, its IBAN, none: BankAccount::exports) are one balance, its newest, never added up (review of 5 October 2026).

pub fn balance(&self) -> Option<(Date, Money)>

The balance of every account together, and the newest day among them.
