Enum TaskStatus 

#[non_exhaustive]
pub enum TaskStatus {
    Submitted,
    Working,
    InputRequired,
    Completed,
    Failed,
    Canceled,
    Rejected,
    Authenticated,
    Unknown,
}

Lifecycle states of a long-running task — A2A spec §6.5.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Submitted

Task accepted, not yet started.

Working

Task is executing.

InputRequired

Task is paused awaiting more user input.

Completed

Task succeeded.

Failed

Task ended with an error.

Canceled

Task was cancelled by the caller.

Rejected

Task was rejected by the server before starting.

Authenticated

Task is waiting on authentication.

Unknown

An unrecognized status from a newer peer. Deserialization maps any unknown wire value here instead of failing, so a forward-version peer can’t break parsing. Never terminal.

Implementations

impl TaskStatus

pub fn is_terminal(&self) -> bool

true if this status cannot transition further. Stream consumers close after observing a terminal status.

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 Copy for TaskStatus

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 Eq for TaskStatus

impl PartialEq for TaskStatus

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

Equality operator ==.

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

Inequality operator !=.

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.
