Struct Ledger 

pub struct Ledger {
    pub told: BTreeMap<String, i64>,
    pub waiting: BTreeMap<String, i64>,
}

What was done with each new message, by key: told (or never to tell), or waiting for a time it may come in; with when. On this device only, in $XDG_STATE_HOME/sioul/mail-notified.toml, forgotten after 30 days.

Fields

told: BTreeMap<String, i64>

waiting: BTreeMap<String, i64>

Implementations

impl Ledger

pub fn default_path() -> PathBuf

pub fn load(path: &Path) -> Ledger

As kept; empty when missing or unreadable (nothing then is told twice but what was waiting, which waits no more).

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

Written whole under another name, then renamed: never half a ledger.

pub fn known(&self, key: &str) -> bool

Whether a message was dealt with already: told, or waiting.

pub fn tell(&mut self, key: &str, at: i64)

Told (or never to tell): never again.

pub fn wait(&mut self, key: &str, at: i64)

Waiting for a time it may come in.

pub fn forget_old(&mut self, now: i64)

Marks older than 30 days forgotten: their mail left the Porch’s view long ago.
