Struct GetTaskPayloadResult 

pub struct GetTaskPayloadResult {
    pub meta: Option<Map<String, Value>>,
    pub extra: Option<Map<String, Value>>,
}

The response to a tasks/result request. The structure matches the result type of the original request. For example, a tools/call task would return the CallToolResult structure.

Implementations

impl GetTaskPayloadResult

pub fn related_task_id(&self) -> Option<&str>

Retrieves the related task ID from the metadata, if it exists.

This function looks for a key corresponding to the RELATED_TASK_META_KEY in the meta field of the struct. If the key exists and contains a string value, it returns it as an Option<&str>. If the key is missing or not a string, it returns None.

Returns

• Some(&str) if a related task ID exists.
• None if no related task ID is found.

pub fn set_related_task_id<T>(&mut self, task_id: T)

where T: Into<String>,

Sets the related task ID in the metadata.

This function inserts a taskId key with the provided task_id into the meta field. If the meta field is None, it creates a new serde_json::Map and assigns it to meta. The task_id is converted into a string before being inserted.

Type Parameters

• T: The type of the task_id. It must implement Into<String> to allow flexible conversion of various types (e.g., &str, String).

Arguments

• task_id: The ID of the related task to set. This can be any type that can be converted into a String.
