Struct CapabilityMemory 

pub struct CapabilityMemory { /* private fields */ }

In-memory store. Keyed by problem_signature. Phase 5 will add persistence; Phase 2 keeps it in RAM.

Implementations

impl CapabilityMemory

pub fn new() -> Self

pub fn lookup(&self, signature: &str) -> Option<&MemoryEntry>

Look up a prior run by problem signature.

pub fn upsert(&mut self, record: CapabilityMemoryRecord, metrics: &ToolMetrics)

Insert or update an entry, accumulating metrics.

pub fn save(&self, path: &Path) -> Result<(), String>

Serialize all entries to a JSON file at path.

pub fn load(path: &Path) -> Result<Self, String>

Load entries from a JSON file. Returns an empty store if the path does not exist (first run). Returns Err only on parse failures.

pub fn len(&self) -> usize

Total number of distinct patterns stored.

pub fn is_empty(&self) -> bool

pub fn derive_signature(req: &CapabilityRequest) -> String

Derive a stable problem signature from a capability request. The signature is capability + input shape + output shape, lowercased and hyphen-joined. It is not a hash — it is human-readable and stable.

Trait Implementations
