Struct Task 

pub struct Task {

    pub id: String,
    pub context_id: String,
    pub state: State,
    pub principal: Option<String>,
    pub link: Link,
    pub message: Option<String>,
    pub ask_schema: Option<Value>,
    pub artifacts: Vec<String>,
    pub result: Option<Value>,
    pub created: u64,
    pub updated: u64,
    pub history: Vec<Value>,
    pub push: Vec<PushTarget>,
    pub dirty: bool,
}

The durable task record.

Fields

id: String

context_id: String

state: State

principal: Option<String>

link: Link

message: Option<String>

The status message (for input-required and terminal explanations).

ask_schema: Option<Value>

The shape a gate’s answer must take (human.schema / ask_human).

Carried on the task because the QUESTION alone does not tell a client how to ask it. With the schema, “pick one of these three” renders as three options instead of a text box the person has to guess the wording for — and the answer is already the right shape when it comes back.

artifacts: Vec<String>

Artifact ids delivered on this task.

result: Option<Value>

The terminal result (a distillate / output).

created: u64

updated: u64

history: Vec<Value>

The transition history (state, ts).

push: Vec<PushTarget>

Where to POST this task’s updates, for a caller that would rather be told than hold a stream open. Durable with the task, so a restart keeps the promise the caller was given.

dirty: bool
