Implementations

impl TaskState

pub const Submitted: Self = Self::TASK_STATE_SUBMITTED

pub const Working: Self = Self::TASK_STATE_WORKING

pub const InputRequired: Self = Self::TASK_STATE_INPUT_REQUIRED

pub const Completed: Self = Self::TASK_STATE_COMPLETED

pub const Canceled: Self = Self::TASK_STATE_CANCELED

pub const Failed: Self = Self::TASK_STATE_FAILED

pub const Rejected: Self = Self::TASK_STATE_REJECTED

pub const AuthRequired: Self = Self::TASK_STATE_AUTH_REQUIRED

pub const Unknown: Self = Self::TASK_STATE_UNSPECIFIED

pub fn is_terminal(&self) -> bool

pub fn is_interrupted(&self) -> bool

The spec’s interrupted states: the agent has stopped and is waiting on the caller. Not terminal — the task resumes once the caller supplies what it asked for — but a caller polling for progress should stop here too.

pub fn is_settled(&self) -> bool

Whether the task has stopped and will not advance on its own — terminal, or interrupted waiting on the caller.

This is the spec’s own stopping condition for a blocking SendMessage: return_immediately = false obliges the server to wait for a terminal or interrupted state (spec/a2a.proto:155). It is also where a subscription ends, and where a polling client stops. Those three had each spelled the condition out separately.

pub fn is_cancelable(&self) -> bool

Whether a client may still cancel a task in this state.

Everything that has not finished: queued (SUBMITTED), running (WORKING), and the interrupted states — cancelling an INPUT_REQUIRED task is exactly how a client says “never mind”. Only the terminal states refuse, because there is nothing left to stop.

Defined here rather than in each storage adapter so the rule has one home: a state added later is cancelable unless it is declared terminal, which is the safe direction to be wrong in — the alternative strands a task no client can get rid of.
