    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 FPS, 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.
