Enum RuntimeError 

#[non_exhaustive]
pub enum RuntimeError {
    NodeRegister(&'static str),
    Spin,
}

Error returned by the codegen-emitted run_plan(runtime) body (Phase 212.N.4) and by Node pkg register(runtime) wrappers (Phase 212.N.7 step-2).

no_std-safe — variants are string-typed so embedded Entry pkgs don’t need to pull thiserror/anyhow to print. The out-of-tree nros-build codegen library re-exports this type so emitted code references ::nros_platform::RuntimeError, NOT ::nros_build::RuntimeError — the embedded Entry pkg’s runtime path then doesn’t need nros-build as a runtime dep (build-dep only).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NodeRegister(&'static str)

A node’s register(runtime) call failed. The string carries the node pkg name.

Phase 212.N.12 hard-renamed the legacy ComponentRegister variant to NodeRegister to match the rclcpp_components / ROS 2 launch.xml <node pkg=…> convention.

Spin

The hosted Entry spin loop failed or did not observe the requested runtime condition before its bounded test deadline.
