#![cfg_attr(docsrs, feature(doc_cfg))]

# persian-rug
When the `"persian-rug"` feature is enabled, a parallel set of types,
traits and derive macros are enabled, i.e. [`BuildableWithPersianRug`]
and [`GeneratableWithPersianRug`]. These provide similar facilities,
but for types based on the [persian-rug](::persian_rug) crate.
Briefly, [persian-rug](::persian_rug) moves ownership of all values
into a single container (the "rug" or
[`Context`](::persian_rug::Context)). Client code then deals with handles
(in the form [`Proxy<T>`](::persian_rug::Proxy)) to these values. The
builders and generators take a mutator for the type's context in their
[`build`](BuilderWithPersianRug::build) and
[`generate`](GeneratorWithPersianRug::generate) methods, which means
at the point of construction, the set of other constructed instances
(of all types in that context) is available.
Since the derived generators pass through
[`Proxy<T>`](::persian_rug::Proxy), and since to get the most benefit from
this system you should work with proxies where possible, the most common
usage is to use these solely through the pass throughs.
Example:
```rust
use boulder::{BuilderWithPersianRug, BuildableWithPersianRug};
use persian_rug::{contextual, persian_rug, Context, Proxy};
#[persian_rug]
struct Rug(
#[table] Foo,
#[table] Bar,
);
#[contextual(Rug)]
#[derive(BuildableWithPersianRug)]
#[boulder(persian_rug(context=Rug))]
struct Foo {
#[boulder(default=5)]
pub a: i32,
#[boulder(buildable_with_persian_rug(a=5))]
pub b: Proxy<Bar>,
}
#[contextual(Rug)]
#[derive(BuildableWithPersianRug)]
#[boulder(persian_rug(context=Rug))]
struct Bar {
#[boulder(default=2)]
pub a: i32
}
let mut r = Rug(Default::default(), Default::default());
let (f, _) = Proxy::<Foo>::builder()
.a(27)
.build(&mut r);
assert_eq!(r.get(&f).a, 27);
assert_eq!(r.get(&r.get(&f).b).a, 5);
```
