Crate derive_builder_core

Important Note:

  • You are probably looking for the derive_builder crate, which wraps this crate and is much more ergonomic to use.
  • The API of this crate might change frequently in the near future. The derive_builder crate also provides a much more stable API.

Purpose

This is an internal helper library of derive_builder. Its purpose is to allow derive_builder to use its own code generation technique, if needed.

derive_builder_core might also be used in crates that derive_builder depends on - to break a dependency cycle.

If derive_builder does not itself depend on your crate, then you should consider using derive_builder instead of derive_builder_core.

Documentation

Please refer to docs.rs/derive_builder_core for the documentation of all published versions.
