Struct TrajectoryView 

pub struct TrajectoryView<'a, T: R2lTensor> {
    pub states: &'a [T],
    pub next_states: &'a [T],
    pub actions: &'a [T],
    pub rewards: &'a [f32],
    pub terminated: &'a [bool],
    pub truncated: &'a [bool],
}

Borrowed view over the aligned fields of a TrajectoryBuffer.

Fields

states: &'a [T]

Observations before each action.

next_states: &'a [T]

Observations after each action.

actions: &'a [T]

Actions selected at each step.

rewards: &'a [f32]

Rewards produced at each step.

terminated: &'a [bool]

Terminal-state flags for each step.

truncated: &'a [bool]

Truncation flags for each step.

Implementations

impl<T: R2lTensor> TrajectoryView<'_, T>

pub fn dones(&self) -> impl Iterator<Item = bool>

Iterates over combined termination and truncation flags.

pub fn episode_terminations(&self) -> usize

Counts transitions that end an episode.

Trait Implementations

impl<T: R2lTensor> TrajectoryBatch<T> for TrajectoryView<'_, T>

fn len(&self) -> usize

Returns the number of transitions in the batch.

fn is_empty(&self) -> bool

Returns true when the batch contains no transitions.

fn states(&self) -> &[T]

Returns observations before each action.

fn next_states(&self) -> &[T]

Returns observations after each action.

fn actions(&self) -> &[T]

Returns actions selected at each step.

fn rewards(&self) -> &[f32]

Returns rewards produced at each step.

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

Returns terminal-state flags for each step.

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

Returns truncation flags for each step.
