Struct FileStateStore 

pub struct FileStateStore { /* private fields */ }

File-based implementation of StateStore.

Stores adapter snapshots as JSON files with atomic write semantics.

Atomic Writes

Uses write-to-temp-then-rename pattern to prevent corruption:

1. Write to {path}.tmp
2. Rename {path}.tmp to {path}

This ensures the file is either fully written or not written at all.

Implementations
