# Dependency Injection container for Rust

[![Build Status](https://travis-ci.org/Nercury/di-rs.svg?branch=master)](https://travis-ci.org/Nercury/di-rs)

This library implements dependency injection container for Rust
mimicking the way it is done in other languages and
frameworks.

It differs from other popular implementations by providing
a simple way to group factories together using `one_of` method.

## Example

```rust
let mut registry = di::Registry::new();

registry
    .one_of("values", || -> i32 { 1 })
    .with_id("a")
    .insert();

registry
    .one_of("values", |a: i32| -> i32 { a + 2 })
    .with_arg("a")
    .insert();

match registry.compile() {
    Ok(container) => {
        if let Some(a) = container.get::<Vec<i32>>("values") {
            assert_eq!(vec![ 1, 1 + 2 ], a.take());
        }
    },
    Err(errors) => di::error_printer::pretty_print(&errors),
}
```

Of course, ungrouped dependencies are also available.

## Usage

Put this in your `Cargo.toml`:

```toml
[dependencies]
di = "*"
```

And this in your crate root:

```rust
extern crate di;
```
