rlmesh::spaces

A SpaceSpec is immutable data describing a space. A Space is a spec plus its sampler, a shared handle whose clones drive one RNG. Box, Discrete and Dict are typed views of a Space (they deref to it) that add their kind’s accessors.

use rlmesh::spaces::{Box, BoxOptions, Dict, Discrete, DiscreteOptions, SpaceSpec};

let pos = Box::new(-1.0, 1.0, [3], BoxOptions::default())?;
let id = Discrete::new(4, DiscreteOptions { start: 1, ..Default::default() })?;
let obs = Dict::new([("pos", SpaceSpec::from(&pos)), ("id", SpaceSpec::from(&id))])?;
obs.seed(Some(7));
let x = obs.sample()?;
assert!(obs.contains(&x));

This module is not in the prelude: spaces::Box shadows std’s Box.

Values are Values: a Box samples a Tensor, a Discrete an Int, a Dict a dict in its declaration order, a Text a Text.
