A Rust crate providing a derive macro that automatically generates builder-pattern code for structs. It creates fluent setter methods and a build() constructor to simplify struct instantiation.

Use cases

• generate builder methods for rust structs
• avoid long constructor argument lists in rust
• implement the builder pattern via derive macro
• create structs with optional fields and defaults
• reduce boilerplate when constructing complex structs

When to choose

• you want automatic builder generation from struct definitions
• you need setter methods with sensible defaults and optional fields
• you prefer a declarative derive macro over hand-written builders

When to avoid

• your structs are simple and constructors suffice
• you need builders for enums or non-struct types
• you want runtime-configurable builders rather than compile-time generation
