zerocopy-derive: Fix panic with raw identifiers #2788
Conversation
Stripped `r#` prefix from identifiers when generating internal field/variant names in `zerocopy-derive`. This prevents panics when using raw identifiers (e.g., `r#type`) in structs or enums. Added regression tests in `zerocopy-derive/tests/struct_known_layout.rs` and `zerocopy-derive/tests/enum_try_from_bytes.rs`. Closes #2234

Factor out logic to strip `r#` prefix from identifiers into `to_ident_str` helper in `zerocopy-derive/src/ext.rs`. Use this helper in `zerocopy-derive/src/lib.rs` and `zerocopy-derive/src/enum.rs` when generating internal identifiers. This prevents panics when using raw identifiers (e.g., `r#type`) in structs or enums. Added regression tests in `zerocopy-derive/tests/struct_known_layout.rs` and `zerocopy-derive/tests/enum_try_from_bytes.rs`.

Fixed a bug where using raw identifiers (e.g.
r#type) as field names in structs or variants in enums causedzerocopy-deriveto panic. The panic occurred because the macro was attempting to create new identifiers by concatenating a prefix with the raw identifier string (includingr#), resulting in invalid identifiers like__Zerocopy_Field_r#type. The fix involves stripping ther#prefix before concatenation. Regression tests were added tozerocopy-derive/tests/struct_known_layout.rsandzerocopy-derive/tests/enum_try_from_bytes.rs.Closes #2234
