Enum TaskStatus 

pub enum TaskStatus {
    Working,
    InputRequired,
    Completed,
    Failed,
    Cancelled,
}

Task status representing the current state of a long-running operation

State Transitions

Valid transitions:

• Working → InputRequired, Completed, Failed, Cancelled
• InputRequired → Working, Completed, Failed, Cancelled
• Terminal states (Completed, Failed, Cancelled) → NO TRANSITIONS

Examples

use turbomcp_protocol::types::tasks::TaskStatus;

let status = TaskStatus::Working;
assert!(!status.is_terminal());

let status = TaskStatus::Completed;
assert!(status.is_terminal());

Variants

Working

Request is currently being processed

InputRequired

Task requires additional input from requestor (e.g., user confirmation)

When in this state:

• Requestor should call tasks/result which will receive input requests
• All input requests MUST include io.modelcontextprotocol/related-task metadata
• After providing input, task transitions back to Working

Completed

Request completed successfully

This is a terminal state - no further transitions allowed.

Failed

Request did not complete successfully

This is a terminal state. The status_message field typically contains diagnostic information about the failure.

Cancelled

Request was cancelled before completion

This is a terminal state. The status_message field may contain the reason for cancellation.

Implementations

impl TaskStatus

pub fn is_terminal(&self) -> bool

Check if this status is terminal (no further transitions allowed)

Terminal states: Completed, Failed, Cancelled

pub fn is_active(&self) -> bool

Check if this status indicates the task is still active

Active states: Working, InputRequired

pub fn can_transition_to(&self, _next: &TaskStatus) -> bool

Check if task can transition to the given status

Examples

use turbomcp_protocol::types::tasks::TaskStatus;

let working = TaskStatus::Working;
assert!(working.can_transition_to(&TaskStatus::Completed));
assert!(working.can_transition_to(&TaskStatus::InputRequired));

let completed = TaskStatus::Completed;
assert!(!completed.can_transition_to(&TaskStatus::Working)); // Terminal

Trait Implementations

impl Clone for TaskStatus

fn clone(&self) -> TaskStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskStatus

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TaskStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TaskStatus

fn eq(&self, other: &TaskStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TaskStatus

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TaskStatus
