Struct MemoryStorage

pub struct MemoryStorage { /* private fields */ }

In-memory storage implementation.

This storage implementation stores all data in a thread-safe HashMap, making it suitable for unit tests and scenarios where persistent storage is not needed.

Path Normalization

The storage normalizes paths to handle various formats:

• memory://path/to/file -> path/to/file
• memory:/path/to/file -> path/to/file
• /path/to/file -> path/to/file
• path/to/file -> path/to/file

Serialization

When serialized, MemoryStorage serializes to an empty state. When deserialized, it creates a new empty instance. This is intentional because in-memory data cannot be meaningfully serialized across process boundaries.

Implementations

impl MemoryStorage

pub fn new() -> Self

Create a new empty MemoryStorage instance.
