Struct CreateTaskResult 

pub struct CreateTaskResult {
    pub task: Task,
    pub _meta: Option<HashMap<String, Value>>,
}

Result type for task creation (immediate response to task-augmented requests)

When a request is augmented with task metadata, the receiver responds immediately with this result containing the task object. The actual operation result is available later via tasks/result.

Two-Phase Response Pattern

Phase 1 (Immediate):
  Client → tools/call (task: {...})
  Server → CreateTaskResult (task with status: working)

Phase 2 (Deferred):
  Client → tasks/result (taskId)
  Server → CallToolResult (actual tool response)

Examples

use turbomcp_protocol::types::tasks::{CreateTaskResult, Task, TaskStatus};

let response = CreateTaskResult {
    task: Task {
        task_id: "task-abc123".to_string(),
        status: TaskStatus::Working,
        status_message: None,
        created_at: "2025-11-25T10:30:00Z".to_string(),
        ttl: Some(60_000),
        poll_interval: Some(5_000),
    },
    _meta: None,
};

Fields

task: Task

The created task with initial state (typically Working)

_meta: Option<HashMap<String, Value>>

Optional metadata

Host applications can use io.modelcontextprotocol/model-immediate-response to provide immediate feedback to the model before task completion.
