axum-password-worker

A module providing a password hashing and verification worker.

This module contains the PasswordWorker struct, which manages bcrypt hashing and verification operations using a combination of a rayon thread pool and crossbeam-channel to efficiently handle these operations asynchronously.

The methods will not block the tokio runtime. All await operations do not block. They use non-blocking channel implementations to send and receive passwords and hashes to the rayon thread pool.

PasswordWorker is Send + Sync + Clone and contains no lifetimes, so it can be used as axum state without an Arc.

Example

```rust

[tokio::main]

async fn main() -> Result<(), Box> { use axumpasswordworker::PasswordWorker;

let password = "hunter2";
let cost = 12; // bcrypt cost value
let max_threads = 4; // rayon thread pool max threads
let password_worker = PasswordWorker::new(max_threads)?;

let hashed_password = password_worker.hash(password, cost).await?;
println!("Hashed password: {:?}", hashed_password);

let is_valid = password_worker.verify(password, hashed_password).await?;
println!("Verification result: {:?}", is_valid);

Ok(())

} ```
