Trait Tool 

pub trait Tool:
    Send
    + Sync
    + 'static {
    // Required methods
    fn descriptor(&self) -> &ToolDescriptor;
    fn invoke<'life0, 'life1, 'async_trait>(
        &'life0 self,
        args: Value,
        ctx: &'life1 InvokeCtx,
    ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

A tool the agent may call. Tools are also Callable, so they can stand in as workflow steps.

Required Methods

fn descriptor(&self) -> &ToolDescriptor

fn invoke<'life0, 'life1, 'async_trait>( &'life0 self, args: Value, ctx: &'life1 InvokeCtx, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<T: RichTool> Tool for T

Any RichTool is automatically a Tool: invoke projects ToolReturn::Content (or the content field of ContentAndArtifact); other variants surface as a synthetic content carrying the control payload, so legacy callers keep working.
