pub fn runtime_error(message: &str) -> !👎Deprecated since 1.1.0:
a module may not end the application; return exception(out, source, message) instead
Expand description
Raise a fatal module error, taking the whole host process down.
Deprecated as of 2026-08-28, and not for modules to call. A module
may never end the application — see
docs/todo/errors-as-particles.md. Report a failure by returning an
exception instead, which the program receives as an ordinary value
and may examine or ignore.
Kept only because runtime.c itself still uses it internally for
conditions with no frame to return to (out of memory). It will leave
this crate’s API entirely once the C runtime has an error channel.
