Struct Snapshot 

pub struct Snapshot {
    pub v: u8,
    pub session_id: String,
    pub revision: i64,
    pub columns: i64,
    pub rows: i64,
    pub cursor: Option<Cursor>,
    pub root_ids: Vec<String>,
    pub nodes: Vec<Node>,
    pub coordinate_space: Option<Observation<String>>,
    pub hit_grid: Option<Observation<PointerHitGrid>>,
}

The whole tree for one committed render.

Fields

v: u8

Snapshot format version; always 1.

session_id: String

Session this snapshot belongs to.

revision: i64

Render revision, strictly increasing per session.

columns: i64

Viewport width in cells.

rows: i64

Viewport height in cells.

cursor: Option<Cursor>

Cursor position, when the app reports one.

root_ids: Vec<String>

Ids of the parentless nodes, in document order.

nodes: Vec<Node>

Every node in the tree.

coordinate_space: Option<Observation<String>>

Qualified coordinate space for all known geometry in protocol v2.

hit_grid: Option<Observation<PointerHitGrid>>

Exact fresh-pointer ownership map for protocol v2, when supported.

Implementations

impl Snapshot

pub fn new(columns: i64, rows: i64) -> Self

An empty snapshot for a viewport. The session id and revision are filled in by crate::Client::publish.

pub fn new_v2(columns: i64, rows: i64) -> Self

Empty qualified v2 snapshot. Every appended node still needs Geometry.

pub fn push(&mut self, node: Node)

Append a node, recording it as a root when it declares no parent.
