Enum ChannelState 

pub enum ChannelState {
    Running,
    Paused,
    AwaitingApproval {
        request_id: String,
    },
    Completed,
    Aborted {
        reason: String,
    },
}

State of a channel.

Channels start in Running state and can transition through various states. Terminal states are Completed and Aborted.

State Transitions

From	To	Method
Running	Completed	ChannelMut::complete()
Running	Aborted	ChannelMut::abort()
Running	Paused	ChannelMut::pause()
Running	AwaitingApproval	ChannelMut::await_approval()
Paused	Running	ChannelMut::resume()
AwaitingApproval	Running	ChannelMut::resolve_approval()
AwaitingApproval	Aborted	ChannelMut::abort() (rejected)

Variants

Running

Channel is actively running.

Paused

Channel is paused.

Can be resumed with ChannelMut::resume().

AwaitingApproval

Channel is waiting for Human approval (HIL).

Approval is a core part of the Channel lifecycle: LLM tool calls require human authorization before execution. This is not an external concern but an intrinsic state of the orchestration flow.

Fields

request_id: String

ID of the approval request.

Completed

Channel completed successfully.

Aborted

Channel was aborted with a reason.

The reason string provides context for debugging and logging.

Fields

reason: String

Explanation of why the channel was aborted.

Trait Implementations

impl Clone for ChannelState

fn clone(&self) -> ChannelState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelState

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

Formats the value using the given formatter.

impl PartialEq for ChannelState

fn eq(&self, other: &ChannelState) -> 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.
