Trait relearn::envs::BuildEnv

pub trait BuildEnv {
    type Observation;
    type Action;
    type ObservationSpace: Space<Element = Self::Observation>;
    type ActionSpace: Space<Element = Self::Action>;
    type Environment: Environment<Observation = Self::Observation, Action = Self::Action> + EnvStructure<ObservationSpace = Self::ObservationSpace, ActionSpace = Self::ActionSpace>;
    fn build_env(&self, seed: u64) -> Result<Self::Environment, BuildEnvError>;
}

Build an Environment.

Environment is an associated trait rather than a generic parameter to facilitate reproducibility: a given environment configuration can construct exactly one environment. The user does not need to store the environment type.

Associated Types

type Observation

Environment observation type.

type Action

Environment action type.

type ObservationSpace: Space<Element = Self::Observation>

Environment observation space type.

type ActionSpace: Space<Element = Self::Action>

Environment action space type.

type Environment: Environment<Observation = Self::Observation, Action = Self::Action> + EnvStructure<ObservationSpace = Self::ObservationSpace, ActionSpace = Self::ActionSpace>

Type of environment to build

Required methods

fn build_env(&self, seed: u64) -> Result<Self::Environment, BuildEnvError>

Build an environment instance.

Args

• seed - Seed for pseudo-randomness in the environment state and transition dynamics. The environment structure itself should not be random; seed any structural randomness from the environment configuration.
