pub fn local(dir: impl AsRef<Path>) -> Result<Self, String>

Create a plugin using a LocalBackend rooted at dir.

pub fn upload( &self, data: &[u8], content_type: &str, original_name: &str, ) -> Result<FileInfo, String>

Upload a file. Returns a FileInfo describing the stored object.

pub fn download(&self, id: &str) -> Result<Vec<u8>, String>

Download the raw bytes of a stored file.

pub fn delete(&self, id: &str) -> Result<bool, String>

Delete a file by ID. Returns true if it existed.

pub fn get_metadata(&self, id: &str) -> Option<FileMetadata>

pub fn list_files(&self) -> Vec<String>

List all stored file IDs.

pub fn exists(&self, id: &str) -> bool

Check whether a file exists.

Trait Implementations

impl Plugin for FileStoragePlugin

fn name(&self) -> &str

Unique name for this plugin.

fn on_init(&self, _ctx: &PluginContext)

Called once when the plugin is registered.

fn routes(&self) -> Vec<PluginRoute>

Custom API routes this plugin handles.

fn before_insert( &self, _entity: &str, _data: &mut Value, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity insert. Return Err to reject.

fn after_insert( &self, _entity: &str, _id: &str, _data: &Value, _auth: &AuthContext, )

Called after a successful insert.

fn before_update( &self, _entity: &str, _id: &str, _data: &mut Value, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity update. Return Err to reject.

fn after_update( &self, _entity: &str, _id: &str, _data: &Value, _auth: &AuthContext, )

Called after a successful update.

fn before_delete( &self, _entity: &str, _id: &str, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity delete. Return Err to reject.

fn after_delete(&self, _entity: &str, _id: &str, _auth: &AuthContext)

Called after a successful delete.

fn on_request( &self, _method: &str, _path: &str, _auth: &AuthContext, ) -> Result<(), PluginError>

Called on every incoming request (middleware).

fn on_request_with_meta( &self, method: &str, path: &str, auth: &AuthContext, _meta: &RequestMeta<'_>, ) -> Result<(), PluginError>

Richer variant of [on_request] that also receives per-request metadata (peer IP today; more fields may be added later). The default implementation delegates to on_request so existing plugins keep working without changes. Plugins that care about IP — notably rate limiting — override this hook.

fn on_session_create(&self, _user_id: &str, _token: &str)

Called when a new session is created.

fn entities(&self) -> Vec<ManifestEntity>

Additional manifest entities this plugin contributes.
