Enum TaskPhase 

#[non_exhaustive]
pub enum TaskPhase {
    Pending,
    Running,
    Succeeded,
    Failed,
    Timeout,
    Canceled,
    Exhausted,
}

Current execution phase of a single task attempt.

Phases describe the state of the current attempt.

Also

• TaskStatus carries the current phase.
• TaskPhase::is_terminal checks for final states.
• RestartPolicy governs what happens after a terminal phase.

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.

Pending

Task is queued or waiting to start.

Running

Task is currently executing.

Succeeded

Task completed successfully.

Failed

Attempt failed with an error.

Timeout

Task exceeded its timeout limit.

Canceled

Task was explicitly canceled.

Exhausted

Task exhausted its restart budget and will not retry.

Implementations

impl TaskPhase

pub fn is_terminal(&self) -> bool

Returns true if the current attempt has reached a final state.

A terminal phase means this attempt will not transition further. The supervisor may still start a new attempt based on the RestartPolicy.

pub fn is_active(&self) -> bool

Returns true if the task is still active (pending or running).

Trait Implementations

impl Clone for TaskPhase

fn clone(&self) -> TaskPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskPhase

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskPhase

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TaskPhase

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

Formats the value using the given formatter.

impl FromStr for TaskPhase

fn from_str(s: &str) -> ModelResult<Self>

Parse a phase name (case-insensitive, trimmed). Accepts the same camelCase form produced by fmt::Display / serde.

type Err = ModelError

The associated error which can be returned from parsing.

impl Hash for TaskPhase

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 TaskPhase

fn eq(&self, other: &TaskPhase) -> 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 TaskPhase

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 TaskPhase
