# 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`].
