impl Attachments for AttachmentStore

fn put<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, owner_type: &'life1 str, owner_id: &'life2 str, field: &'life3 str, file: UploadedFile, ) -> Pin<Box<dyn Future<Output = Result<Attachment, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Store (or replace) the file attached to owner_type/owner_id under field, returning the stored metadata.

fn get<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, owner_type: &'life1 str, owner_id: &'life2 str, field: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Attachment>, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

The attachment stored under a single field, if any.

fn list<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, owner_type: &'life1 str, owner_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<Attachment>, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Every attachment for a record, across all fields.

fn read<'life0, 'life1, 'async_trait>( &'life0 self, storage_key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetch the raw bytes for a stored attachment.

fn delete<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, owner_type: &'life1 str, owner_id: &'life2 str, field: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Remove one field’s attachment (bytes and metadata). A no-op if absent.

fn delete_all<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, owner_type: &'life1 str, owner_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Remove all attachments for a record. Called when the record itself is deleted, so blobs don’t outlive their owner.
