Struct FileMemoryStore 

pub struct FileMemoryStore { /* private fields */ }

File-backed memory store with per-level validators.

Directory layout:

base_dir/L0/...
base_dir/L1/...
...

Paths passed to read/write/patch/delete are relative to a level directory. The format is <level_prefix>/<name>, e.g. "L1/key_info.md". The level prefix is automatically stripped to resolve the filesystem path.

Implementations

impl FileMemoryStore

pub fn new(base_dir: impl Into<PathBuf>) -> Self

Create a new file-backed store rooted at base_dir. Level subdirectories are created lazily on first write.

pub fn with_validator( self, level: MemoryLevel, validator: Box<dyn MemoryValidator>, ) -> Self

Attach a validator for a specific memory level.
