Struct ExperienceTable 

pub struct ExperienceTable { /* private fields */ }

Append-only columnar table for RL transitions.

All data is stored in flat Vec<f32> arrays for efficient export to numpy. The table only appends, never reallocating existing data in-place.

Implementations

impl ExperienceTable

pub fn new(obs_dim: usize, act_dim: usize) -> Self

Create a new table with the given observation and action dimensions.

pub fn obs_dim(&self) -> usize

Observation dimensionality.

pub fn act_dim(&self) -> usize

Action dimensionality.

pub fn len(&self) -> usize

Number of transitions stored.

pub fn is_empty(&self) -> bool

Whether the table is empty.

pub fn push_slices( &mut self, obs: &[f32], next_obs: &[f32], action: &[f32], reward: f32, terminated: bool, truncated: bool, ) -> Result<(), RloxError>

Append a transition from borrowed slices, avoiding intermediate allocation.

pub fn push(&mut self, record: ExperienceRecord) -> Result<(), RloxError>

Append a single transition. Returns error on dimension mismatch.

pub fn observations_raw(&self) -> &[f32]

Raw slice of all observation data. Shape: [count * obs_dim].

pub fn actions_raw(&self) -> &[f32]

Raw slice of all action data. Shape: [count * act_dim].

pub fn rewards_raw(&self) -> &[f32]

Raw slice of all rewards.

pub fn terminated(&self) -> &[bool]

Slice of terminated flags.

pub fn truncated(&self) -> &[bool]

Slice of truncated flags.

pub fn clear(&mut self)

Drop all stored data.
