Module kind 

Canonical kind strings for tagged condition values.

These constants are emitted into the kind slot of make_rust_condition_value and consumed by the R-side .miniextendr_raise_condition switch (see registry::write_r_wrappers_to_file). Reference these constants from codegen and runtime sites instead of bare string literals so a typo cannot silently change which switch arm fires.

The constants are kept in lockstep with the generated R helper; if a new kind is added, both the emission site and the R helper need to learn it.

Constants

CONDITION

User-raised condition!(...) condition.

CONVERSION

TryFromSexp / coerce / strict-mode conversion failed at argument unmarshalling.

ERROR

User-raised error!(...) condition.

MESSAGE

User-raised message!(...) condition.

NONE_ERR

Option<T>::None reached where a value was required (raised by the NoneOnErr / required-Option return paths).

OTHER_RUST_ERROR

Fallback kind written by super::make_rust_condition_value when the caller’s kind argument contained an interior NUL and could not be converted to a CString. Should not appear in normal flow; the match arm in [crate::condition::RCondition::from_sexp] handles it defensively by degrading to RCondition::Error.

PANIC

Default kind for Rust panics that surface to R via the generic panic path (no RCondition payload). Layered as rust_error.

RESULT_ERR

Result<_, E>::Err(...) formatted via Debug (raised when the user returns an Err from a #[miniextendr] fn/method).

WARNING

User-raised warning!(...) condition.
