Struct InMemoryMetadataStore

pub struct InMemoryMetadataStore { /* private fields */ }

In‑memory implementation of MetadataStore backed by a HashMap.

What: Holds metadata in a hash map where the key is the file path.

How: Provides a new constructor and implements the MetadataStore trait methods by delegating to the underlying map.

Why: Offers a zero‑cost, dependency‑free store suitable for unit tests and simple scenarios. It can be replaced with a persistent store without changing callers.

Implementations

impl InMemoryMetadataStore

pub fn new() -> Self

Creates a fresh, empty InMemoryMetadataStore.

What: Returns a struct with an empty internal map.

How: Calls HashMap::new.

Why: Convenience constructor for callers.
