Struct Set 

pub struct Set { /* private fields */ }

Every host anybody has an opinion about, by name.

A map rather than a list because the question asked of it is always about one name, and because the order it iterates in is then the order the startup banner prints.

Implementations

impl Set

pub fn new(configured: Vec<Host>) -> Self

The configured hosts, with any remembered changes of mind applied over them.

pub fn get(&self, name: &str) -> Option<&Host>

This host, if it is enabled.

Disabled reads the same as absent, which is what lets a caller treat “turned off” and “never mentioned” alike without writing the distinction down anywhere.

pub fn enabled(&self) -> impl Iterator<Item = &Host>

Every enabled host, for the daemon to open at startup.

pub fn set(&mut self, name: &str, enabled: bool, base: Option<String>)

Turn one on or off.

Remembering it is a separate call: a state directory that cannot be written must not undo a change the reader can already see working.
