Struct SpacePolicy 

pub struct SpacePolicy(/* private fields */);

A study’s growth policy: which parameters are open, and how – one Open per name, in BTreeMap name order for the same determinism reason crate::space::Assignment documents. Serializes transparently as that name-to-policy map, with no extra wrapper layer.

use atune_core::space::{Open, SpacePolicy};

let policy = SpacePolicy::new()
    .insert("lr", Open::log(1e-5..=1e-2).up().limit(..=1.0))?
    .insert("width", Open::linear(64.0..=512.0).down())?;

assert!(policy.get("lr").is_some());
assert_eq!(policy.get("batch_size"), None);

Implementations

impl SpacePolicy

pub const fn new() -> Self

An empty policy: no parameter is open.

pub fn insert(self, name: impl Into<String>, open: Open) -> Result<Self>

Declares name open under open, validating it first (§7.3, §7.4, §9.6 – see Open::validate). Chainable; a later call for the same name replaces the earlier one.

Errors

Whatever Open::validate returns for open.

pub fn get(&self, name: &str) -> Option<&Open>

The policy declared for name, if any.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Open)>

Every (name, policy) pair, in name order — the map’s own deterministic iteration, for the create-time persistence walk and widen’s per-parameter reads.

pub fn is_empty(&self) -> bool

true when no parameter is declared open.
