# 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
```rust
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
