pub struct PageState {

    pub url: String,
    pub engine_handle: PageHandle,
    pub last_tree: Option<Tree>,

    pub force_full: bool,
    pub seen_refs: HashSet<Ref>,
}

In-memory page state.

Fields

id: String

url: String

engine_handle: PageHandle

last_tree: Option<Tree>

The last tree we emitted to the agent. None until the first vs_view.

last_token: Option<StateToken>

Token corresponding to last_tree, or to the post-mutation state if a write just landed.

force_full: bool

Whether the next vs_view must emit a fresh full tree (e.g. after nav, viewport change, or auth_loaded).

seen_refs: HashSet<Ref>

Refs ever seen on this page, for retire-tracking.

Implementations

impl PageState

pub fn new(id: String, url: String, engine_handle: PageHandle) -> Self

pub fn invalidate_baseline(&mut self)

Mark the next view as a fresh-full re-baseline.

pub fn apply_snapshot(&mut self, new_tree: Tree) -> (StateToken, ViewForm)

Apply a fresh snapshot from the engine. Returns the new token and the ViewForm the agent should receive.

pub fn find_node(&self, r: Ref) -> Option<&Node>

Find a node by ref in the most recent tree. Used by vs_read.
