Struct RunnerError 

pub struct RunnerError { /* private fields */ }

A failure to run learner code: the interpreter could not be spawned, or its output pipes could not be read.

Distinct from a program that ran and failed — that is an ExecutionResult with a non-zero exit. Kept a typed error so core stays free of anyhow (ADR-0001).
