Implementations

impl AttachmentProcessor

pub fn new(config: AttachmentConfig) -> Self

Create a new attachment processor with the given configuration

pub fn is_enabled(&self) -> bool

Check if attachment processing is enabled

pub fn total_size(&self) -> usize

Get the current total size

pub fn count(&self) -> usize

Get the number of processed attachments

pub fn skipped_count(&self) -> usize

Get the number of skipped attachments

pub fn process_attachments( &mut self, message_id: i64, attachments: &[AttachmentData], ) -> Result<Vec<String>>

Process attachments from a message

Returns a list of blob hashes that were successfully processed. Attachments that exceed size limits or have disallowed MIME types are logged and skipped.

pub fn write_encrypted_blobs( &self, output_dir: &Path, dek: &[u8; 32], export_id: &[u8; 16], ) -> Result<AttachmentManifest>

Write encrypted blobs to the output directory

Each blob is encrypted with AES-256-GCM using:

• DEK: Same data encryption key as main database
• Nonce: Derived from blob hash using HKDF
• AAD: export_id || hash bytes
