This is the rust-version declared by recent versions of Syn.
Reduce scope of quote_spanned on SerializeWith wrapper
Rename field_names_idents -> field_idents_aliases
Mingun and others added 30 commits September 21, 2025 20:40
Refactor: split de generator over multiple files
No longer macro_use integer128 module
Remove InPlaceSeed public re-export
Inline serde_core into serde in docsrs mode
Workaround for RUSTDOCFLAGS='--cfg=docsrs'
This may slightly improve compilation time and costs nothing
Remove some ? from generated code
