Struct SnapshotMetadata 

pub struct SnapshotMetadata {
    pub components: BTreeMap<&'static str, f32>,
    pub positions: BTreeMap<&'static str, [f32; 3]>,
}

Named metadata emitted alongside a snapshot.

Used for shaped / multi-component reward logging. Keys are &'static str constants defined in each per-environment module to avoid magic strings at call sites.

Fields

components: BTreeMap<&'static str, f32>

Named reward components (e.g. "ctrl", "goal", "healthy").

positions: BTreeMap<&'static str, [f32; 3]>

Named 3D positions for analysis (e.g. "torso", "com", "main_body").

Implementations

impl SnapshotMetadata

pub fn new() -> Self

Creates an empty SnapshotMetadata.

pub fn with(self, key: &'static str, value: f32) -> Self

Builder-style insert for a named reward component.

pub fn with_position(self, key: &'static str, xyz: [f32; 3]) -> Self

Builder-style insert for a named 3D position.
