Struct IncrementalUpdate 

pub struct IncrementalUpdate {
    pub sequence: u64,
    pub time: f64,
    pub changed_bodies: Vec<SimBodyState>,
    pub removed_handles: Vec<u32>,
    pub added_handles: Vec<u32>,
}

An incremental state update (delta) for efficient streaming.

Instead of sending the full snapshot every frame, only changed bodies are included in the delta.

Fields

sequence: u64

Sequence number for ordering.

time: f64

Timestamp of this update.

changed_bodies: Vec<SimBodyState>

Only bodies that changed since the last update.

removed_handles: Vec<u32>

Handles of bodies that were removed.

added_handles: Vec<u32>

Handles of bodies that were added.

pub fn to_json(&self) -> String

Serialize to JSON.

pub fn from_json(json: &str) -> Result<Self, Error>

Deserialize from JSON.

pub fn is_empty(&self) -> bool
