Provided Methods§

Source

fn crash_context_prefix(&self) -> Option<RcStr>

Optional human-readable prefix describing what was being evaluated, included verbatim in the message of the synthetic StructuredError emitted when the Node.js subprocess crashes mid-evaluation. For webpack-loader evaluations this is the loader chain (“loaders [foo, bar]”). The default returns None.
