fn check_s7_shortcut_collisions(parsed: &ParsedImpl) -> Result<()>Expand description
Detect S7 fast-path shortcut name collisions within an inherent impl block.
The S7 generator (s7_class) emits a standalone <ClassName>_<method>
shortcut function for each non-fallback, non-no_shortcut instance method,
and a <ClassName>_<r_method_name> function for each static method. These
share one R namespace, so two definitions with the same name silently
clobber each other (last write wins). This typically arises from an
r_name override that aliases an instance shortcut onto a static method
(or vice versa).
Returns an error pointing at the offending method, advising the user to
rename (via r_name) or opt the instance method out with
#[miniextendr(s7(no_shortcut))]. Non-S7 class systems are a no-op.
Note: collisions with #[derive(ExternalPtr)] sidecar accessors
(<ClassName>_get_<field> / _set_<field>) are not detected here — the
sidecar field names live in the derive’s distributed-slice registry and are
not visible to this macro invocation. See #991 for the write-time check.
