Represents an environment, typically an MDP.

Associated Types

type Config: Clone

Configurations.

type Obs: Obs

Observation of the environment.

type Act: Act

Action of the environment.

type Info: Info

Information in the self::Step object.

Required methods

fn build(config: &Self::Config, seed: i64) -> Result<Self> where
    Self: Sized, 

Builds an environment with a given random seed.

fn step(&mut self, a: &Self::Act) -> (Step<Self>, Record) where
    Self: Sized, 

Performes an environment step.

fn reset(&mut self, is_done: Option<&Vec<i8>>) -> Result<Self::Obs>

Resets the environment if is_done[0] == 1. or is_done.is_none().

Old versions of the library supports vectorized environments and is_done was used to reset a part of the vectorized environments. Currenly, vecorized environment is not supported and is_done.len() is expected to be 1.

fn step_with_reset(&mut self, a: &Self::Act) -> (Step<Self>, Record) where
    Self: Sized, 

Performes an environment step and reset the environment if an episode ends.
