Coobjc
coobjc es una biblioteca de corrutinas para Objective-C que proporciona métodos await y generadores para simplificar la programación asíncrona en Objective-C y Swift. Permite la implementación de flujos de trabajo no bloqueantes para eliminar callbacks anidados y el bloqueo de hilos.
El kit de herramientas incluye un wrapper no bloqueante de Foundation para convertir APIs síncronas de Foundation y UIKit en operaciones suspendibles. Proporciona un generador de secuencias lazy para producir valores bajo demanda mediante yield, así como una herramienta de comunicación basada en canales para intercambiar datos entre tareas concurrentes usando canales con y sin buffer.
La biblioteca cubre la coordinación de tareas asíncronas y la gestión de estado, utilizando un modelo de actores para prevenir condiciones de carrera. Sus capacidades incluyen la programación de corrutinas, cancelación y la capacidad de ejecutar operaciones de sistema de archivos y red sin congelar la interfaz de usuario.
Features
- Asynchronous Programming - Enables non-blocking workflows in Objective-C and Swift through the implementation of coroutines and await methods.
- Asynchronous Message Passings - Provides an actor model where isolated entities exchange data exclusively through asynchronous message passing.
- Custom Data Channels - Implements communication primitives for exchanging data between concurrent tasks using buffered and unbuffered channels.
- Asynchronous Flow Coordination - Provides patterns for managing the synchronization and resolution of concurrent asynchronous operations.
- Coroutine Launchers - Enables initiating the execution of asynchronous coroutine blocks on specific target queues.
- Lazy Sequences - Provides lazy sequence generators that produce values on demand via yield to handle large data sets efficiently.
- Coroutine Libraries - Provides a comprehensive coroutine library for managing cooperative multitasking and lightweight threads in Objective-C and Swift.
- Block-Based Coroutines - Transforms asynchronous code blocks into state machines to enable non-blocking suspension and resumption.
- Native API Wrappers - Wraps synchronous system APIs into non-blocking operations to maintain user interface responsiveness.
- Non-Blocking API Wrappers - Converts synchronous system calls into suspendable operations compatible with a coroutine runtime.
- Actor-Based Concurrency - Uses isolated, message-passing actors to manage state and execution without data races.
- Asynchronous Task Managers - Offers tools for coordinating complex execution flows using await methods and channels to synchronize concurrent tasks.
- Coroutine Task Schedulers - Manages a queue of lightweight coroutines and distributes them across worker pools for efficiency.
- Lock-Free State Management - Utilizes an actor model to manage shared state and prevent data races in Apple ecosystem applications.
- Coroutine Communication Channels - Provides communication channels for exchanging signals and data between concurrent coroutines.
- CSP Communication Channels - Provides synchronization primitives based on communicating sequential processes for data exchange between concurrent tasks.
- Lazy Sequence Processing - Implements a lazy sequence generator to produce values on demand, reducing memory allocation for large data sets.
- Coroutine Result Awaiting - Allows suspending a coroutine until a promise or channel resolves to return a value.
- Sequential Task Execution - Executes a series of asynchronous computations in a strict linear order to prevent nested callbacks.
- Lazy Data Scanning - Defers data processing until requested to ensure the system only handles data when the consumer is ready.
- Asynchronous Sequence Generators - Implements generators that produce sequences of values where each element is fetched via an async operation.
- Coroutine Suspension Controls - Enables suspending tasks and restoring them later from the last known state using custom calling stacks.
- Custom Execution Stacks - Implements custom call-stack management to restore task state after await calls.
- Lazy Evaluation - Implements lazy evaluation to produce data sequences one item at a time and reduce memory overhead.
- Coroutine Termination - Implements a mechanism to cooperatively stop executing coroutines and perform necessary cleanup.
- Non-blocking IO Implementations - Provides non-blocking implementations for file system and networking operations to maintain user interface responsiveness.
- Asynchronous File I/O - Provides non-blocking interfaces for reading and writing files without stalling the execution thread.
