[−][src]Crate derive_builder_core

Internal helper library for the derive_builder crate.

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 - again 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.

Bindings	Bindings to be used by the generated code.
Block	A permissive wrapper for expressions/blocks, implementing `quote::ToTokens`.
BuildMethod	Initializer for the struct fields in the build method, implementing `quote::ToTokens`.
Builder	Builder, implementing `quote::ToTokens`.
BuilderField	Field for the builder struct, implementing `quote::ToTokens`.
DeprecationNotes	Deprecation notes we want to emit to the user, implementing `quote::ToTokens`.
Initializer	Initializer for the target struct fields, implementing `quote::ToTokens`.
Setter	Setter for the struct fields in the build method, implementing `quote::ToTokens`.

Controls the signature of a setter method, more specifically how self is passed and returned.

Doc-comment, implementing quote::ToTokens.
