Enum TaskState 

#[non_exhaustive]
pub enum TaskState {
    Submitted,
    Working,
    Completed,
    Failed,
    Canceled,
    InputRequired,
    Rejected,
    AuthRequired,
}

A2A task states — type-safe wrapper over proto TaskState.

Excludes UNSPECIFIED which is not a valid application state.

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.

Implementations

impl TaskState

pub fn can_transition_to(&self, next: TaskState) -> bool

Returns whether transitioning from self to next is valid per the A2A spec.

pub fn is_terminal(&self) -> bool

Returns true if this is a terminal state (no further transitions allowed).

Trait Implementations

impl Clone for TaskState

fn clone(&self) -> TaskState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskState

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

Formats the value using the given formatter.

impl From<TaskState> for TaskState

fn from(value: TaskState) -> Self

Converts to this type from the input type.

impl Hash for TaskState

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 TaskState

fn eq(&self, other: &TaskState) -> 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 TryFrom<TaskState> for TaskState

type Error = A2aTypeError

The type returned in the event of a conversion error.

fn try_from(value: TaskState) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<i32> for TaskState

type Error = A2aTypeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
