# Goners
# Core-Level Goners
Core components are also Goners that can be injected into other Goners. These Goners are essential for the operation of Gone and are indispensable parts of the framework.
| Interface | Implementation | GoneId | Description |
|---|---|---|---|
| Heaven (opens new window) | heaven (opens new window) | gone-heaven | Responsible for resurrecting Goners from the cemetery, executing installed Hook functions, and managing the framework's startup and shutdown processes and states. |
| Cemetery (opens new window) | cemetery (opens new window) | gone-cemetery | Manages Goners and provides the Bury method for burying Goners. The dependency injection logic is mainly implemented in this structure. |
# Built-in Framework Goners
Built-in framework Goners are developed to enrich the functionality of Gone, such as supporting web development, database connections, Redis, etc. The code is implemented in the goner directory (opens new window). Each subdirectory under this directory implements a feature of Gone, each containing the definition and implementation of one or more Goners.
For ease of use, we have defined the Priest function in goner/priest.go (opens new window), which can directly bury related Goners in batches according to functionality.
