Module registry 

Tool trait + Registry — the contract third-party implementers see.

Structs

PaginatedResult

Result of a paginated tool call. Tools that don’t paginate return next_cursor: None; the default Tool::call_paginated impl wraps Tool::call to produce this shape automatically.

RegisteredTool

One registered tool plus the binding dispatch uses to execute it. SP-12 Task 4: Binding sits between dispatch and the Tool impl so the same tool can be served via different execution strategies (in-process, CLI subprocess, future MCP / REST / AppFunction).

Registry

Traits

Tool

A tool. One impl Tool for MyTool per tool; registered once at startup. Tools MUST NOT panic; they return Err(ToolCallError) instead.

Type Aliases

CallFuture

Boxed future returned by Tool::call.

PaginatedCallFuture

Boxed future returned by Tool::call_paginated. SP-pagination-v1 §4.4.
