Struct EpisodeRecord 

pub struct EpisodeRecord {
    pub total_reward: f64,
    pub length: usize,
    pub status: EpisodeStatus,
    pub extras: HashMap<String, f64>,
}

Total undiscounted reward for the episode.

length: usize

Number of steps in the episode.

status: EpisodeStatus

How the episode ended.

extras: HashMap<String, f64>

Arbitrary scalar extras provided by the user or environment.
