Struct CreateTaskResult 

pub struct CreateTaskResult {
    pub task: TaskObject,
    pub meta: Option<Value>,
}

Result of creating a task (returned when tools/call is task-augmented).

Per SEP-2663, CreateTaskResult = Result & Task: the task fields are inlined at the top of the result and resultType is set to "task" so clients can distinguish a task handle from a normal CallToolResult on the same RPC.

Serialization layout:

{
  "resultType": "task",
  "taskId": "...",
  "status": "working",
  "createdAt": "...",
  "lastUpdatedAt": "...",
  "ttl": null,
  "pollInterval": 5000,
  // The nested `task` field is emitted purely for back-compat with the
  // 2025-11-25 experimental wire format. New clients should read the
  // top-level fields and ignore `task`. This nested mirror will be
  // removed in a future release.
  "task": { "taskId": ..., "status": ..., ... }
}

Fields

task: TaskObject

The created task object. Serialized both inline (per SEP-2663) and under the legacy task key for back-compat.

meta: Option<Value>

Optional protocol-level metadata

Implementations

impl CreateTaskResult

pub const RESULT_TYPE: &'static str = RESULT_TYPE_TASK

Wire-spec discriminator value (always "task").

pub fn new(task: TaskObject) -> CreateTaskResult

Build a result from a TaskObject, with the SEP-2663 discriminator pre-populated when serialized.
