Struct SnapshotDict 

pub struct SnapshotDict {
    pub version: u32,
    pub time: f64,
    pub gravity: [f64; 3],
    pub bodies: Vec<BodyDict>,
    pub n_contacts: usize,
    pub description: Option<String>,
}

A Python-dict-compatible representation of a SimulationSnapshot.

The to_dict_json method returns a JSON string structured like a Python dict that the Python side can eval() or json.loads() directly.

Fields

version: u32

Snapshot version.

time: f64

Simulation time.

gravity: [f64; 3]

Gravity as list.

bodies: Vec<BodyDict>

Body states as list of dicts.

n_contacts: usize

Number of contacts.

description: Option<String>

Optional description.

Implementations

impl SnapshotDict

pub fn from_snapshot(snap: &SimulationSnapshot) -> Self
