data-record-rs

A procedural macro that auto-generates traits and implementations for your structs, enabling Java record–like behavior in Rust. It creates:

• A getter trait containing one method per named field.
• A constructor trait with a canonical constructor (default name new).

This allows you to keep struct fields private while providing read-only access and a standardized way to construct instances.

Features

• Getter Trait Generation:
  For each named field in your struct, a corresponding method is added to the generated getter trait.

• Constructor Trait Generation:
  A constructor trait is generated with a method (default: new, customizable) that takes each field as an argument and returns an instance of the struct.

• Custom Attributes:
  Fine-tune the generated code by applying custom attributes to:

  • The getter trait definition (datarecord_getter_attr)
  • The getter trait implementation (datarecord_getter_impl_attr)
  • The constructor trait definition (datarecord_const_attr)
  • The constructor trait implementation (datarecordgit_const_impl_attr)
  • The constructor method (datarecord_const_impl_method_attr)

Requirements

• A Rust toolchain that supports procedural macros
