please

A simple Rust library providing convenient builder pattern utilities.

Overview

please offers two main functions for creating and initializing objects:

• build() - Creates a new instance using the type’s Default implementation
• build_with() - Creates a new instance and applies a custom initializer function

Usage

Add this to your Cargo.toml:

[dependencies]
please = "0.1.0"

Examples

Basic usage with build():

use please::build;

#[derive(Default)]
struct Person {
    name: String,
    age: i32,
}

let person = build::<Person>();
// Creates Person { name: "", age: 0 }

Custom initialization with build_with():

use please::build_with;

let person = build_with(|p: &mut Person| {
    p.name = String::from("Alice");
    p.age = 30;
});
// Creates Person { name: "Alice", age: 30 }

Requirements

• Rust 2024 edition
• Types must implement Default trait
