    E: Env,
    P: StepProcessorBase<E>,{ /* private fields */ }

Gets an Agent interacts with an Env and takes samples.

Implementations

impl<E, P> SyncSampler<E, P>where E: Env, P: StepProcessorBase<E>,

pub fn new(env: E, producer: P) -> Self

Creates a sampler.

pub fn sample_and_push<A, R, R_>( &mut self, agent: &mut A, buffer: &mut R_ ) -> Result<Record>where A: Agent<E, R>, R: ReplayBufferBase<PushedItem = P::Output>, R_: ReplayBufferBase<PushedItem = R::PushedItem>,

Samples transitions and pushes them into the replay buffer.

The replay buffer R_, to which samples will be pushed, has to accept PushedItem that are the same with Agent::R.

pub fn fps(&self) -> f32

Returns frames per second, including taking action, applying it to the environment, producing transition, and pushing it into the replay buffer.

pub fn reset(&mut self)

Reset stats for computing FPS.
