Concurrency

Concurrency in Drift allows you to execute multiple tasks simultaneously, improving performance and responsiveness in your applications. Drift's concurrency model is designed to make parallel execution safer and more intuitive.

warning

At this moment, Drift does not implement concurrency features.

// Example of how concurrency might look in Drift
async fun fetchData(url: String) : String {
    // Asynchronous operation
    return await networkRequest(url)
}

// Running tasks in parallel
fun processMultipleUrls(urls: [String]) {
    let results = parallel {            // Concurrent block returning values
        for urls { as url
            fetchData(url)
        }
    }
    
    // Process results after all tasks complete
    for results { as result
        print(result)
    }
}

Concurrent Blocks:

• parallel runs async-capable expression statements, each statement must return a value. The block will return a tuple with each returned value.
• concurrent runs async-capable expression statements without returning a tuple.

In both cases, on error throwing, the entire block will be canceled.

Concurrency Features

Drift's concurrency model will include:

• Asynchronous functions with async/await syntax
• Parallel execution of tasks
• Thread safety mechanisms
• Structured concurrency for better resource management
• Built-in synchronization primitives
