As procedural macros can be distributed as crates, a lot of emerging helpful macro crates are available, which can be found at crates.io. Using them can greatly reduce the boilerplate you need to write for generating Rust code. Some of them are as follows:

  • derive-new: A derive macro provides a default all-fields constructor for structs and is quite customizable.
  • derive-more: A derive macro that circumvents the limitation where we wrap a type for which we already have a lot of traits auto-implemented, but lose the ability to create our own type wrapping for it. This crate helps us provide the same set of traits, even on these wrapper types.
