Enum ToolOutcome 

pub enum ToolOutcome<T> {
    Output(T),
    Suspend(Suspension),
}

The Ok side of a tool call: either the tool’s normal output, or a Suspension.

Suspension is modeled here, on the success side, and not as a ToolError. A parked run is a normal, expected outcome of a human-in-the-loop tool, not a failure, and the runtime loop treats the two branches differently: an Output feeds the next model turn, a Suspend records a Suspended event and parks the run. Encoding that split in the type keeps the loop from having to guess.

The typed layer produces ToolOutcome<Self::Output>; the type-erased layer produces ToolOutcome<serde_json::Value>. The Suspend branch is identical across both, so a suspension crosses the erasure boundary unchanged.

Variants

Output(T)

The tool finished and produced this output.

Suspend(Suspension)

The tool asks to park the run and wait for the described input.
