Module-level declarations

Simple module to support delayed events by adding an event entity and then extend and listen to the callback.

Types

delay_type

enum delay_type

delayed_event

entity delayed_event

Deprecated entity, replaced by scheduled_callback. Remove once migrated.

scheduled_event

entity scheduled_event

Each entity represents a scheduled event to be triggered at a specific time. It is however not part of the delay implementation, but used to keep the time and later turn it into a delayed event.

Functions

add_scheduled_event

function add_scheduled_event(delay_type: delay_type, ref_id: integer, scheduled_at: integer)

Store information about a scheduled event. This will not execute it on time, just store it.

being_block_delay_migration_wrapper

@extend(on_begin_block) function being_block_delay_migration_wrapper(height: integer)

delete_scheduled_event

function delete_scheduled_event(delay_type: delay_type, ref_id: integer)

get_scheduled_event_delay

function get_scheduled_event_delay(delay_type: delay_type, ref_id: integer): integer?

Get the approximately time (delay) from "now" (last block time) to the scheduled_at time.

get_scheduled_event_time

function get_scheduled_event_time(delay_type: delay_type, ref_id: integer): integer?

migrate_delays_to_scheduled_callbacks

function migrate_delays_to_scheduled_callbacks()
