Struct CheckpointWriter 

Source 
pub struct CheckpointWriter {
    pub bodies: Vec<BodyDesc>,
    pub sim_time: f64,
    pub step: u64,
    pub metadata: Vec<(String, String)>,
}
Expand description

A simulation checkpoint: full state including bodies, constraints, and broadphase.

Fields§

§bodies: Vec<BodyDesc>

Bodies in the checkpoint.

§sim_time: f64

Simulation time.

§step: u64

Simulation step count.

§metadata: Vec<(String, String)>

Extra metadata key-value pairs.

Source

pub fn add_metadata(&mut self, key: &str, value: &str)

Add metadata.

Source

pub fn write_json<W: Write>(&self, w: &mut W) -> Result<()>

Write checkpoint as JSON.
