AssembledToolCallFromTool: AssembledToolCallFromToolCall<ToolCallFromTool<T>, InferToolOutput<T>>Infer the streaming AssembledToolCall handle for a single LangChain tool.
Parallel to ToolCallFromTool for message-level tool calls —
use this when a component receives one entry from stream.toolCalls
and you know which tool definition it came from.
const searchWeb = tool(/* ... */);
function SearchWebCall({ toolCall }: {
toolCall: AssembledToolCallFromTool<typeof searchWeb>;
}) {
// toolCall.name is "search_web", args/input are schema-inferred
}
v1 framework packages (`@langchain/react`, `@langchain/vue`, etc.) re-export
this type as {@link ToolCallFromTool}. {@link AssembledToolCall.output} is
`null` until the call succeeds; use {@link status} / {@link error} for UI.
