Trait Run 

pub trait Run<B: NixBackend> {
    type Error: 'static + Error + Send + Sync;

    // Required method
    fn run<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,

Core trait of runix

Implemented for commands that may take a reference of a NixBackend to run a nix command.

Example

Following example implements Run for a Command on the MyBackend backend.

struct MyBackend;
struct Command;
impl NixBackend for MyBackend {}

#[async_trait::async_trait]
impl Run<MyBackend> for Command {
    type Error = io::Error;

    async fn run(&self, _backend: &MyBackend, _nix_args: &NixArgs) -> Result<(), io::Error> {
        panic!("42")
        // backend.run_in_nix(args)
    }
}

#[tokio::main]
async fn main() {
    Command
        .run(&MyBackend, &NixArgs {
            ..Default::default()
        })
        .await
        .unwrap()
}
