Struct Checkpoint 

pub struct Checkpoint {
    pub time: SimTime,
    pub step: u64,
    pub data: Vec<u8>,
    pub hash: [u8; 32],
    pub rng_state: RngState,
}

Checkpoint with compressed state.

Fields

time: SimTime

Simulation time at checkpoint.

step: u64

Step count at checkpoint.

data: Vec<u8>

Compressed state data.

hash: [u8; 32]

Blake3 hash for integrity verification.

rng_state: RngState

RNG state for replay.

Implementations

impl Checkpoint

pub fn create( time: SimTime, step: u64, state: &SimState, rng_state: RngState, compression_level: i32, ) -> SimResult<Self>

Create a new checkpoint from state.

Errors

Returns error if serialization or compression fails.

pub fn restore(&self) -> SimResult<SimState>

Restore state from checkpoint.

Errors

Returns error if integrity check fails or deserialization fails.

pub fn compressed_size(&self) -> usize

Get compressed size in bytes.
