Struct AppPreferencesDocument

pub struct AppPreferencesDocument {
    pub version: u32,
    pub values: BTreeMap<String, Value>,
}

Versioned, extensible application-preferences payload.

Values are ordered by key for deterministic in-memory traversal and JSON serialization. Empty values are valid. Deserialization preserves any version; AppStorage::read_preferences performs compatibility validation.

Examples

use ailloli_ui_app_storage::AppPreferencesDocument;
use serde_json::json;
let mut preferences = AppPreferencesDocument::new();
preferences.values.insert("theme".into(), json!("dark"));
assert_eq!(preferences.values["theme"], "dark");

Fields

version: u32

Persisted schema version; the current supported value is APP_PREFERENCES_VERSION.

values: BTreeMap<String, Value>

Application-defined JSON preferences; an empty map means no saved preferences.

Implementations

impl AppPreferencesDocument

pub fn new() -> Self

Creates a current-version document with no preference values.

Examples

use ailloli_ui_app_storage::{AppPreferencesDocument, APP_PREFERENCES_VERSION};
let document = AppPreferencesDocument::new();
assert_eq!(document.version, APP_PREFERENCES_VERSION);
assert!(document.values.is_empty());

Trait Implementations

impl Clone for AppPreferencesDocument

fn clone(&self) -> AppPreferencesDocument

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AppPreferencesDocument

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

Formats the value using the given formatter.

impl Default for AppPreferencesDocument

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AppPreferencesDocument

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AppPreferencesDocument

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AppPreferencesDocument

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
