Enum TaskState 

pub enum TaskState {
    Runnable(TaskIntent),
    InSend {
        task_id: String,
    },
    InReply {
        task_id: String,
    },
    Completed(HarnessOutcome),
    Faulted(Fault),
}

State machine for task lifecycle.

Valid transitions:

• Runnable -> InSend
• InSend -> InReply
• InReply -> Completed | Faulted
• Any non-terminal -> Faulted

Variants

Runnable(TaskIntent)

InSend

Fields

task_id: String

InReply

Fields

task_id: String

Completed(HarnessOutcome)

Faulted(Fault)

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<'de> Deserialize<'de> for TaskState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for TaskState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
