Trait for records that expose persistence-related callback hooks.

Provided Methods

fn before_save_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run before save operations.

fn after_save_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run after save operations.

fn before_create_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run before create operations.

fn after_create_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run after create operations.

fn before_update_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run before update operations.

fn after_update_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run after update operations.

fn before_destroy_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run before destroy operations.

fn after_destroy_callbacks() -> &'static [fn(&mut Self) -> CallbackResult]

Returns callbacks that run after destroy operations.

fn callbacks_for( event: ModelEvent, ) -> &'static [fn(&mut Self) -> CallbackResult]

Returns the raw callback list for the given lifecycle event.

fn callback_chain(event: ModelEvent) -> CallbackChain<Self>

Builds a callback chain for the requested lifecycle event.

fn run_callbacks(&mut self, event: ModelEvent) -> CallbackResult

Runs the callbacks registered for the requested lifecycle event.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
