Struct Task 

pub struct Task {
    pub task_id: String,
    pub status: TaskStatus,
    pub status_message: Option<String>,
    pub created_at: Option<String>,
    pub last_updated_at: Option<String>,
    pub ttl: Option<u64>,
    pub poll_interval: Option<u64>,
}

Represents an asynchronous task (MCP 2025-11-25 experimental)

Tasks enable long-running operations that can be polled for status, cancelled, and have their results retrieved asynchronously.

Fields

task_id: String

Unique identifier for the task

status: TaskStatus

Current execution status

status_message: Option<String>

Optional human-readable status description

created_at: Option<String>

ISO 8601 timestamp of task creation

last_updated_at: Option<String>

ISO 8601 timestamp of last status change

ttl: Option<u64>

Time-to-live in seconds before automatic cleanup

poll_interval: Option<u64>

Suggested polling interval in milliseconds
