Module tool

Expand description

Tool dispatch — regular, streaming, and input-streaming tools.

Modules§

commit: Commit governance for a tool that acts on the world: idempotency and compensation.
context: What a tool knows about the call it serves.
dispatcher: Tool dispatcher — routes function calls to the right tool implementation.
media: Tool media returns — the ADK pattern where a function response carries images or other media to the model alongside its JSON payload, so vision tools (screenshots, chart renderers, document croppers) feed the model something it can actually look at.
policy: Per-tool execution policy — timeout, caching, and confirmation.
schema: One schema pipeline from Rust types to the Gemini wire format.
simple: Simple function tool that wraps an async closure.
typed: Type-safe function tool with auto-generated JSON Schema.

ActiveStreamingTool: Handle to a running streaming tool.
CommitGuard: A tool wrapped with idempotency and compensation. See the module docs.
ContextTool: A tool from a closure that receives the ToolContext.
PolicyTool: A ToolFunction decorator that enforces a ToolPolicy.
SimpleTool: Simple function tool that wraps an async closure.
ToolContext: The session a tool call runs in.
ToolDispatcher: Routes function calls to the right tool implementation.
ToolPolicy: Optional per-tool execution policy.
TypedTool: Type-safe function tool with auto-generated JSON Schema.

InputStreamingTool: An input-streaming tool — receives duplicated live input while running.
StreamingTool: A streaming tool — runs in background, yields multiple results.
ToolFunction: A regular tool — called once, returns a result.

wire_schema: Derive a JSON Schema in the shape the Gemini API will actually enforce.
