    pub lang: Option<Lang>,
    pub core: CorePreferences,
    pub welcomed: bool,

}

Everything one person settled about their own copy of the city.

Whole rather than a dozen readings, because that is the record the file holds and because a screen that changes two of these at once must not be able to write one and drop the other.

This is the grammar of [ui] in the person’s own file as well as the shape of the answer. The file is read through this type and written by serialising it, so a key the file may hold and a field the answer states are one declaration. A section that states only some of them is read with the rest at the postures PreferencesAnswer::default gives, and a key no field claims is refused where it is written rather than ignored into a setting that never takes effect.

Fields

lang: Option<Lang>

The language this person reads the interface in, and nothing when they have never said.

Absent rather than a language this build picked for them: the browser’s own tag is the only evidence anybody has before the first choice, and a stated en here would overrule it on every machine whose owner simply never opened the setting.

core: CorePreferences

Performance settings read from [core], never stored in [ui].

welcomed: bool

Whether this person has walked through the welcome once. The city decides whether setting up is needed; this only decides whether somebody who skipped it is asked again.

panel: bool

Whether the panel beside a conversation is open.

tier: Option<Tier>

The tier this person last chose, and nothing when they never chose one: the tier a first visit opens in is the page’s posture, and a stated tier here would overrule it on every machine whose owner never pressed the key.

appearance: Appearance

proxying: Proxying

Which proxy rule an endpoint attached from now on starts with. An endpoint already attached keeps the rule the city recorded for it.

chords: Vec<Chord>

The chords this person rebound, action order.

tags: Vec<SessionTags>

The tags this person gave sessions, in session order (crates/wire/spec/Preference.lean §8-84).

theme: ThemeOverride

The person’s colours laid over the built-in theme (crates/wire/spec/Preference.lean D29).

Implementations

impl PreferencesAnswer

pub fn apply(&mut self, patch: PreferencePatch)

Lands one named change on this record.

Here rather than at the file: what a patch means is the patch’s own rule, and a second application of it — in the store, in a test, in whatever keeps these next — would be a second answer to what Chord("") does.

Trait Implementations

impl Clone for PreferencesAnswer

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PreferencesAnswer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PreferencesAnswer

What a person who has settled nothing is answered.

The postures this build draws before anybody chooses, stated once for the file’s reader and the answer’s reader together. panel is the one that is not its type’s own default: the panel beside a conversation is open until somebody closes it, so an unwritten file has to say true where welcomed says false.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PreferencesAnswer

where PreferencesAnswer: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PreferencesAnswer

impl PartialEq for PreferencesAnswer

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for PreferencesAnswer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
