Struct Switch 

pub struct Switch {
    pub device: BTreeMap<String, Device>,
    pub other: Table,
}

The switch’s file: a table per device.

Fields

device: BTreeMap<String, Device>

other: Table

What a later version writes here, kept as it is.

Implementations

impl Switch

pub fn default_path() -> PathBuf

pub fn read(path: &Path) -> Result<Switch, String>

The file as it is; none there is no press anywhere yet. One that does not read is an error: never taken for no device at all.

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

For a question (the status line, an apply): what cannot be read is no press.

pub fn latest(&self) -> Option<Press>

The latest press anywhere wins; one that did not know of an opposite press made on another device less than MARGIN_MS before it gives way to it if that one was “on”.

pub fn latest_known(&self, except: Option<&str>) -> i64

The latest press known here, of any device but except (milliseconds).

pub fn press(&mut self, here: &str, on: bool, until: i64, now_ms: i64) -> i64

A press here, stamped after every press known (a hybrid clock): until in milliseconds, 0 for none. Returns its stamp.

pub fn press_via( &mut self, here: &str, on: bool, until: i64, now_ms: i64, via: &str, ) -> i64

A press here, as press, saying where it came from (VIA_SYSTEM: this device’s own do-not-disturb, heard as it changed; “”: the switch).

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

Written whole, beside it then put in place: never half a file.

Trait Implementations
