Struct AdaptedPlugin 

pub struct AdaptedPlugin { /* private fields */ }

Available on crate feature plugin only.

Wraps a legacy closure-based Plugin as an EnhancedPlugin.

This adapter enables existing plugins to participate in the enhanced pipeline without modification. Legacy callbacks are invoked for their side effects, but the adapter does not modify tool arguments or results (legacy callbacks don’t have access to them).

For model hooks, the adapter maps between the legacy BeforeModelResult and the new BeforeModelCallResult, preserving short-circuit semantics.

Implementations

impl AdaptedPlugin

pub fn new(plugin: Plugin, priority: i32) -> AdaptedPlugin

Create a new adapter wrapping a legacy plugin with the given priority.

Arguments

• plugin - The legacy Plugin to wrap
• priority - Execution priority (lower values execute first, default: 100)

Example

use adk_plugin::{AdaptedPlugin, Plugin, PluginConfig};

let plugin = Plugin::new(PluginConfig {
    name: "logger".to_string(),
    ..Default::default()
});

let adapted = AdaptedPlugin::new(plugin, 50);
assert_eq!(adapted.priority(), 50);

Trait Implementations

impl EnhancedPlugin for AdaptedPlugin

fn name(&self) -> &str

Unique name identifying this plugin.

fn priority(&self) -> i32

Execution priority. Lower values execute first. Default: 100.

fn before_tool_call<'life0, 'life1, 'async_trait>( &'life0 self, _tool: Arc<dyn Tool>, args: Value, ctx: Arc<dyn CallbackContext>, _plugin_ctx: &'life1 PluginContext, ) -> Pin<Box<dyn Future<Output = Result<BeforeToolCallResult, AdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, AdaptedPlugin: 'async_trait,

Called before a tool is executed.

fn after_tool_call<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _tool: Arc<dyn Tool>, _args: &'life1 Value, result: Value, ctx: Arc<dyn CallbackContext>, _plugin_ctx: &'life2 PluginContext, ) -> Pin<Box<dyn Future<Output = Result<AfterToolCallResult, AdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, AdaptedPlugin: 'async_trait,

Called after a tool executes successfully.

fn before_model_call<'life0, 'life1, 'async_trait>( &'life0 self, request: LlmRequest, ctx: Arc<dyn CallbackContext>, _plugin_ctx: &'life1 PluginContext, ) -> Pin<Box<dyn Future<Output = Result<BeforeModelCallResult, AdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, AdaptedPlugin: 'async_trait,

Called before a model (LLM) call is made.

fn after_model_call<'life0, 'life1, 'async_trait>( &'life0 self, response: LlmResponse, ctx: Arc<dyn CallbackContext>, _plugin_ctx: &'life1 PluginContext, ) -> Pin<Box<dyn Future<Output = Result<AfterModelCallResult, AdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, AdaptedPlugin: 'async_trait,

Called after a model (LLM) call completes.

fn close<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, AdaptedPlugin: 'async_trait,

Called when the plugin is being shut down.
