The trait which defines the needed methods an environment needs to provide

Required methods

fn step(&mut self, action: ActionType) -> (Vec<f64>, f64, bool, Option<String>)[src]

Run one timestep of the environment’s dynamics. When end of episode is reached, you you are responsible for calling ‘reset()’ to reset this environment’s state

Accepts an action and returns a tuple (observation, reward, done, info)

Returns: observation: agent’s observation of the current environment reward: amount of reward returned after previous action done: whether the episode has ended info: optional information string *

fn reset(&mut self) -> Vec<f64>[src]

Reset the environment to an initial state This function should not reset reset the environment’s random number generator(s) Returns the environments initial state

fn render(&self, viewer: &mut GifRender<'_>)[src]

Render the environment

fn seed(&mut self, seed: u64)[src]

Set the seed for this environments random number generator
