Trait MultiRoundToolHandler 

pub trait MultiRoundToolHandler: Send + Sync {
    // Required method
    fn call<'life0, 'async_trait>(
        &'life0 self,
        call: MultiRoundToolCall,
    ) -> Pin<Box<dyn Future<Output = McpResult<OperationResult<ToolResult>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Handler for tools that may require MCP 2026 multi-round-trip input.

A handler returns OperationResult::Complete when execution is finished, or OperationResult::InputRequired with client input requests and/or opaque request state. The SDK rejects an input-required result on a legacy connection.

Required Methods

fn call<'life0, 'async_trait>( &'life0 self, call: MultiRoundToolCall, ) -> Pin<Box<dyn Future<Output = McpResult<OperationResult<ToolResult>>> + 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".
