Trait ToolHandler 

pub trait ToolHandler:
    Send
    + Sync
    + 'static {
    // Required method
    fn call<'life0, 'async_trait>(
        &'life0 self,
        input: Value,
    ) -> Pin<Box<dyn Future<Output = Result<Value, BlockError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Async handler invoked when the LLM (or a Lua call to tool.call(name, ...)) targets a Rust-implemented tool supplied via BlockConfig::host_tools.

input arrives as a serde_json::Value (converted from Lua before the handler is invoked). The returned value is converted back to a Lua value and delivered to the caller. Errors are propagated as LuaError::external (visible inside the script) and as BlockError on the Rust side.

Required Methods

fn call<'life0, 'async_trait>( &'life0 self, input: Value, ) -> Pin<Box<dyn Future<Output = Result<Value, BlockError>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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