Crate service_builder

Source
Expand description

Service Builder is a lightweight, type-safe service construction library that leverages the builder pattern for dependency injection in Rust.

§Overview

This crate provides a procedural macro for automatically implementing the builder pattern for service initialization. It focuses on compile-time safety, zero-cost abstractions, and idiomatic Rust patterns.

§Features

  • Type-safe dependency injection at compile time
  • Zero runtime overhead
  • Automatic builder implementation via proc-macros
  • Comprehensive error handling

§Example

ⓘ
use service_builder::builder;
use service_builder::error::BuildError;
use std::sync::Arc;

#[builder]
struct UserService {
    repository: Arc<dyn UserRepository>,
    cache: Arc<dyn Cache>,
}

let service = UserService::builder()
    .repository(user_repo)
    .cache(cache)
    .build()?;
