Life Cycles

ivo lets you react to changes on a domain entity or its individual fields. The concepts below are shared across both implementations - see the root README for the full language-agnostic definitions. This page covers how to wire them up in Rust.

onDelete

Manually triggered by invoking the delete method of a schema's model. Subscribe for the entire entity via schema options, or per output field. See the should_properly_trigger_on_delete_handlers and should_properly_trigger_all_on_delete_handlers test functions here.

onFailure

Manually triggered by invoking the handle failure function returned from an unsuccessful create or update operation. Subscribe on individual input fields that have at least one validator.

onSuccess

Manually triggered by invoking the handle success function returned from a successful create or update operation. Subscribe on any individual field, or for a group of fields via schema options (an empty fields array subscribes to changes on the entire entity).

Custom context options

See Getting Started - custom context options for how to thread extra data (dependency injection, caching, i18n, ...) through create/update/delete operations and into these handlers.
