builder_derive_more

Additional Rust procedural macros for the builder pattern.

Instructions

Rust

Add builder_derive_more as a Rust dependency to your Cargo.toml manifest.

[dependencies]
builder_derive_more = "0.1"

Usage

Hereafter, you can #[derive(IntoBuilder)] alongside deriving the builder pattern (e.g. via derive_builder).

use builder_derive_more::IntoBuilder;
use derive_builder::Builder;

#[derive(Builder, IntoBuilder)]
pub struct Foo {
    bar: String,
}

This allows you to convert from the struct with named fields back into the builder for configuration.

// `IntoBuilder` derive provides the `Foo::builder()` and `Foo::configure(self)` methods.
let foo: Foo = Foo::builder().bar("bar").build().unwrap();
let foo_builder: FooBuilder = foo.configure();
