vec_parallel

A library for building vectors in parallel using async tasks.

This crate provides utilities to construct Vec<T> in parallel by dividing the work into multiple async tasks that can run concurrently. This is particularly useful for CPU-bound initialization tasks where elements can be computed independently.

Example

use vec_parallel::{build_vec, Strategy};

// Build a vector of squares using multiple tasks
let builder = build_vec(100, Strategy::TasksPerCore(4), |i| i * i);

// Run the tasks (in a real application, these would be spawned on an executor)
for task in builder.tasks {
    test_executors::spin_on(task);
}

// Get the final result
let squares = test_executors::spin_on(builder.result);
assert_eq!(squares[10], 100); // 10² = 100

Features

• Flexible parallelization strategies: Choose how many tasks to create
• Zero-copy construction: Elements are written directly to their final location
• Executor-agnostic: Works with any async runtime
• Optional executor integration: Use the some_executor feature for convenient spawning
