Struct PickleEnvelope 

pub struct PickleEnvelope {
    pub snapshot: SimulationSnapshot,
}

A Python-pickle-compatible binary envelope for a SimulationSnapshot.

The real pickle protocol uses a complex op-code stream. Here we implement a self-describing binary envelope that can be round-tripped without Python:

[4]  magic  "OXPK"
[1]  version  (currently 2)
[4]  payload_len  (u32 LE)
[payload_len]  JSON-encoded snapshot
[1]  terminal  0x2e  ('.')

Fields

snapshot: SimulationSnapshot

The snapshot stored in this envelope.

Implementations

impl PickleEnvelope

pub fn new(snapshot: SimulationSnapshot) -> Self

Wrap a snapshot in a pickle envelope.

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes.

pub fn from_bytes(data: &[u8]) -> Result<Self, Error>

Deserialize from bytes.

pub fn to_hex(&self) -> String

Serialize to a hex string (for embedding in Python source).

Trait Implementations

impl Clone for PickleEnvelope

fn clone(&self) -> PickleEnvelope

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PickleEnvelope

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
