Trait Sampler 

pub trait Sampler {
    type Tensor: R2lTensor;

    // Required methods
    fn collect_rollouts<A: Actor<Tensor = Self::Tensor> + Clone>(
        &mut self,
        actor: A,
    ) -> Result<(), Error>;
    fn trajectory_views(
        &mut self,
    ) -> impl AsRef<[TrajectoryView<'_, Self::Tensor>]>;

    // Provided method
    fn reset_all_envs(&mut self) -> Result<(), Error> { ... }
}

Rollout collector used by an on-policy training loop.

Required Associated Types

type Tensor: R2lTensor

Tensor type stored in collected trajectories.

Required Methods

fn collect_rollouts<A: Actor<Tensor = Self::Tensor> + Clone>( &mut self, actor: A, ) -> Result<(), Error>

Collects rollout data using the provided actor.

Errors

Returns an error if an environment operation fails during collection.

fn trajectory_views(&mut self) -> impl AsRef<[TrajectoryView<'_, Self::Tensor>]>

Creates a view for the agents.

Provided Methods

fn reset_all_envs(&mut self) -> Result<(), Error>

Resets all environments managed by the sampler.

Errors

Returns an error if an environment cannot be reset.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
