Function execute_tool_calls_parallel 

pub async fn execute_tool_calls_parallel<F, Exec>(
    tool_calls: Vec<ToolCall>,
    executor: Exec,
) -> Vec<Result<ToolResult, Box<dyn Error + Send + Sync>>>
where
    F: Future<Output = Result<ToolResult, Box<dyn Error + Send + Sync>>> + Send + 'static,
    Exec: Fn(ToolCall) -> F,

Executes multiple tool calls in parallel.

Takes a list of tool calls and an executor function, runs them concurrently using tokio::spawn, and returns all results.

Arguments

• tool_calls - List of tool calls to execute
• executor - Async function that executes a single tool call

Type Parameters

• F - Future returned by the executor
• Exec - Executor function type

Returns

Vector of tool results in the same order as input tool calls.

Examples

use api_xai::{ ToolCall, ToolResult, execute_tool_calls_parallel };
use serde_json::json;

// Execute all tool calls in parallel
let results = execute_tool_calls_parallel( tool_calls, | call | async move {
  // Your tool execution logic here
  match call.function.name.as_str() {
    "get_weather" => {
      let result = json!({ "temperature": 72, "conditions": "sunny" });
      Ok( ToolResult::new( call.id, &result ) )
    }
    _ => {
      Err( format!( "Unknown function : {name}", name = call.function.name ).into() )
    }
  }
} ).await;
