Struct EncryptedCachePersistence 

pub struct EncryptedCachePersistence { /* private fields */ }

Encrypted cache persistence using ChaCha20-Poly1305

Wraps the standard CachePersistence with at-rest encryption using a key derived from the HostIdentity (see ADR-007).

Implementations

impl EncryptedCachePersistence

pub fn new( cache_dir: &Path, enable_locking: bool, encryption_key: [u8; 32], ) -> Result<Self>

Create new encrypted persistence layer

Arguments

• cache_dir - Directory for cache files
• enable_locking - Whether to use file locking for coordination
• encryption_key - 32-byte key from HostIdentity::derive_cache_key()

pub fn load(&self) -> Result<CacheData>

Load encrypted cache from disk

pub fn save(&self, cache: &mut CacheData) -> Result<()>

Save cache to disk with encryption

pub fn exists(&self) -> bool

Check if encrypted cache file exists

Trait Implementations

impl Drop for EncryptedCachePersistence

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
