// This file defines the public interface for dynamically loaded plugins.
|
|
|
|
// The plugin needs to do all interaction with the CLI crate through trait
|
|
// objects and function pointers. This ensures that no concrete internal methods
|
|
// (such as register_op and the closures created by it) can end up in the plugin
|
|
// shared library itself, which would cause segfaults when the plugin is
|
|
// unloaded and all functions in the plugin library are unmapped from memory.
