This macro can be used with various builders that use closures for configuration. Macro rewrites only simple method calls without a path and leaves other expressions as-is. It do not touch calls like builder.method(), module::method() or Class::method(). Type parameters work as expected, so you can use method<T>() and the macro converts it to context.method<T>().

Сompatible libraries

1. Rustless — REST-like API micro-framework for Rust. Works with Iron.
2. jsonway — JSON building DSL and configurable serializers for Rust.
3. valico — JSON Schema validator and JSON coercer.
4. Any other library that uses the same pattern for building blocks.

Usage

Source:

rust dsl!(|context, other_arg1, other_arg2, /* .. */| { method_of_context(other_arg1); another_method_of_context(other_arg2); })

Result:

rust |context, other_arg1, other_arg2, /* .. */| { context.method_of_context(other_arg1); context.another_method_of_context(other_arg2); }

Examples

Without DSL:

```rust rustless::Namespace::build("tweets", |tweets| { tweets.get("latest", |endpoint| { endpoint.desc("Get latest tweets"); endpoint.handle(|client, _params| { // body omitted }) });

tweet.post(/* omitted */);
tweet.delete(/* omitted */);

}) ```

With DSL:

```rust rustless::Namespace::build("tweets", dsl!(|tweets| { get("latest", dsl!(|endpoint| { desc("Get latest tweets"); handle(|client, _params| { // body omitted }) }));

post(/* omitted */);
delete(/* omitted */);

})) ```
