Struct CRiAppBuilder 

pub struct CRiAppBuilder { /* private fields */ }

Opaque C wrapper structure for RiAppBuilder.

Provides C-compatible interface to the Rust application builder implementation. The builder uses the fluent builder pattern to construct Ri applications with proper dependency injection and lifecycle management.

Builder Responsibilities

The application builder handles:

• Service registration and dependency management
• Middleware composition and ordering
• Configuration propagation to components
• Lifecycle event registration
• Application initialization and startup coordination

Builder Pattern

The builder implements a fluent interface allowing method chaining:

ri_app_builder_register_module(builder, module_a);
ri_app_builder_register_module(builder, module_b);
ri_app_builder_configure(builder, config);
ri_app_builder_with_middleware(builder, middleware_1);
ri_app_builder_with_middleware(builder, middleware_2);

Thread Safety

The builder is not thread-safe. All builder operations should occur from a single thread before application startup. Concurrent builder access results in undefined behavior.
