NullRuntime โ always-available stub backend.
Used when:
- The Cargo feature
xfa-js-sandboxedis not compiled in. - A caller selects
JsExecutionMode::SandboxedRuntimebut the build did not link a real backend.
Returning SandboxError::NotCompiledIn from every script call
lets the dispatch site fall back to the existing best-effort skip
path (js_skipped += 1, js_runtime_errors += 1) without changing
pipeline behaviour.
Structsยง
- Null
Runtime - Stub runtime that refuses every script call.
