Struct WindowStateDocument

pub struct WindowStateDocument {
    pub version: u32,
    pub windows: Vec<WindowSnapshot>,
}

Versioned set of persisted top-level window snapshots.

An empty vector is valid. Duplicate or empty window identifiers are stored; Self::snapshot_for returns the first exact match. Deserialization preserves any version until AppStorage::read_window_state validates it.

Examples

use ailloli_ui_app_storage::{WindowSnapshot, WindowStateDocument};
let document = WindowStateDocument::new(vec![WindowSnapshot::new("main")]);
assert!(document.snapshot_for("main").is_some());

Fields

version: u32

Persisted schema version; the current supported value is WINDOW_STATE_VERSION.

windows: Vec<WindowSnapshot>

Snapshots in caller-provided order; an empty list represents no saved windows.

Implementations

impl WindowStateDocument

pub fn new(windows: Vec<WindowSnapshot>) -> Self

Creates a current-version document from snapshots stored verbatim.

Examples

use ailloli_ui_app_storage::{WindowSnapshot, WindowStateDocument};
let document = WindowStateDocument::new(vec![WindowSnapshot::new("main")]);
assert_eq!(document.windows.len(), 1);

pub fn empty() -> Self

Creates a current-version document with no snapshots.

Examples

use ailloli_ui_app_storage::WindowStateDocument;
assert!(WindowStateDocument::empty().windows.is_empty());

pub fn snapshot_for(&self, window_id: &str) -> Option<&WindowSnapshot>

Returns the first snapshot whose identifier exactly equals window_id.

Returns None for no match, including when the document is empty. The lookup is linear in the number of windows.

Examples

use ailloli_ui_app_storage::{WindowSnapshot, WindowStateDocument};
let document = WindowStateDocument::new(vec![WindowSnapshot::new("main")]);
assert_eq!(document.snapshot_for("missing"), None);

Trait Implementations

impl Clone for WindowStateDocument

fn clone(&self) -> WindowStateDocument

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowStateDocument

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

Formats the value using the given formatter.

impl Default for WindowStateDocument

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WindowStateDocument

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WindowStateDocument

fn eq(&self, other: &WindowStateDocument) -> 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 WindowStateDocument

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
