pub struct SampledBatch {
    pub observations: Vec<f32>,

    pub rewards: Vec<f32>,

Expand description

A sampled batch of transitions. Owns its data (copied from the ring buffer).

Fields§

§observations: Vec<f32>§next_observations: Vec<f32>§actions: Vec<f32>§rewards: Vec<f32>§terminated: Vec<bool>§truncated: Vec<bool>§obs_dim: usize§act_dim: usize§batch_size: usize§extra: Vec<(String, Vec<f32>)>

Extra column data, populated only when columns are registered. Each entry is (column_name, flat_data) where flat_data has length batch_size * column_dim.

Implementations§

Source§

impl SampledBatch

Source

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

Source

pub fn clear(&mut self)

Clear all data but retain allocated capacity for reuse.

Note: extra is cleared entirely (the outer Vec). If you alternate between buffers with different extra-column schemas, the inner Vecs’ capacity is lost. This is acceptable because cross-buffer reuse of extra columns is uncommon.
