Attribute Macro block_on_proc::block_on

#[block_on]

Generate a blocking method for each async method in an impl block. Supports either tokio or async-std backend. Generated methods are suffixed with _blocking.

Example tokio

use block_on::block_on;

struct Tokio {}

#[block_on("tokio")]
impl Tokio {
    async fn test_async(&self) {}        
}

Generates the following impl block

async fn test_async(&self) {}
         
fn test_async_blocking(&self) {
    use tokio::runtime::Runtime;
    let mut rt = Runtime::new().unwrap();
    rt.block_on(self.test_async())
}

Example async-std

use block_on::block_on;

struct AsyncStd {}

#[block_on("async-std")]
impl AsyncStd {
    async fn test_async(&self) {}        
}

Generates the following method in the same impl block

async fn test_async(&self) {}        

fn test_async_blocking(&self) {
      use async_std::task;
      task::block_on(self.test_async())
}
