Enum SpawnError 

pub enum SpawnError {
    Engine(String),
    InvalidSpec(String),
}

Error returned by crate::execution::ExecutionService::spawn.

Note on #[from] EngineError

In this subtask, the engine-level error is represented as a String wrapper. Subtask 2 will replace Engine(String) with Engine(#[from] SessionError) once the engine’s SessionError type is available, using #[from] for automatic conversion.

Variants

Engine(String)

The engine failed to start the session.

InvalidSpec(String)

The provided SessionSpec was invalid.
