Struct CompositionCache 

pub struct CompositionCache { /* private fields */ }

Persistent cache that maps normalized problem hashes to composition graphs.

Stored as JSON at ~/.noether/compositions.json (or NOETHER_HOME/compositions.json). --force bypasses the cache and always re-runs the LLM.

Implementations

impl CompositionCache

pub fn open(path: impl AsRef<Path>) -> Self

Open or create the cache at path.

pub fn get(&self, problem: &str) -> Option<&CachedComposition>

Look up a problem. Returns None if not cached or cache is empty.

pub fn insert(&mut self, problem: &str, graph: CompositionGraph, model: &str)

Store a new composition result.

pub fn len(&self) -> usize

Number of cached compositions.

pub fn is_empty(&self) -> bool
