The method `MapperBuilder::infer()` can be used to infer an
implementation for a given interface.
The callback given to this method must return the name of a class that
implements the interface. Any arguments can be required by the callback;
they will be mapped properly using the given source.
```php
$mapper = (new \CuyZ\Valinor\MapperBuilder())
->infer(UuidInterface::class, fn () => MyUuid::class)
->infer(SomeInterface::class, fn (string $type) => match($type) {
'first' => FirstImplementation::class,
'second' => SecondImplementation::class,
default => throw new DomainException("Unhandled type `$type`.")
})->mapper();
// Will return an instance of `FirstImplementation`
$mapper->map(SomeInterface::class, [
'type' => 'first',
'uuid' => 'a6868d61-acba-406d-bcff-30ecd8c0ceb6',
'someString' => 'foo',
]);
// Will return an instance of `SecondImplementation`
$mapper->map(SomeInterface::class, [
'type' => 'second',
'uuid' => 'a6868d61-acba-406d-bcff-30ecd8c0ceb6',
'someInt' => 42,
]);
interface SomeInterface {}
final class FirstImplementation implements SomeInterface
{
public readonly UuidInterface $uuid;
public readonly string $someString;
}
final class SecondImplementation implements SomeInterface
{
public readonly UuidInterface $uuid;
public readonly int $someInt;
}
```
