Struct TransitionMeta 

pub struct TransitionMeta {
    pub env_id: u32,
    pub episode_id: u64,
    pub step_in_episode: u32,
    pub global_step: u64,
    pub policy_version: u64,
    pub reward_model_version: u64,
    pub timestamp_ns: u64,
}

Metadata attached to each transition for provenance tracking.

Fixed-size serialization: 48 bytes (little-endian). Layout: env_id(4) + episode_id(8) + step_in_episode(4) + global_step(8) + policy_version(8) + reward_model_version(8) + timestamp_ns(8) = 48

Fields

env_id: u32

episode_id: u64

step_in_episode: u32

global_step: u64

policy_version: u64

reward_model_version: u64

timestamp_ns: u64

Implementations

impl TransitionMeta

pub fn new( env_id: u32, episode_id: u64, step_in_episode: u32, global_step: u64, policy_version: u64, ) -> Self

Create a new TransitionMeta, auto-filling timestamp_ns from the system clock and defaulting reward_model_version to 0.

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

Serialize to a fixed 48-byte little-endian representation.

pub fn deserialize(bytes: &[u8]) -> Result<Self, RloxError>

Deserialize from a 48-byte little-endian buffer.

Trait Implementations

impl Clone for TransitionMeta

fn clone(&self) -> TransitionMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransitionMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransitionMeta

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransitionMeta

fn eq(&self, other: &TransitionMeta) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TransitionMeta

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
