Implementations

impl Wallet

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

The wallet at the root of a notes folder; empty when there is none yet.

pub fn get(&self, id: &str) -> Option<&Paper>

pub fn file_path(&self, paper: &Paper) -> Option<PathBuf>

A paper’s file, where it is on this computer.

pub fn put(&mut self, paper: Paper) -> String

A paper added or changed (by id; a new one gets an id from its title); returns its id.

pub fn remove(&mut self, id: &str) -> bool

A paper taken out of the wallet; its file stays where it is.

pub fn keep_file(&self, source: &Path, name: &str) -> Result<String, String>

A file copied into the wallet’s folder, under a free name; its path from the notes folder.

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

Written whole, next to its place then moved: never half a file. Under the file’s lock.

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