Trait AsPin

pub trait AsPin: Deref {
    // Required method
    fn as_pin(&mut self) -> Pin<&mut Self>;
}

Gets Pin out of value

Usage:

use cute_async::AsPin;

use core::task;
use core::pin::Pin;
use core::future::Future;

pub struct MyFuture<T>(T);

impl<T: AsPin + Unpin + Future> Future for MyFuture<T> {
    type Output = T::Output;

    fn poll(mut self: Pin<&mut Self>, ctx: &mut task::Context<'_>) -> task::Poll<Self::Output> {
        let inner = self.0.as_pin();
        Future::poll(inner, ctx)
    }
}

Required Methods

fn as_pin(&mut self) -> Pin<&mut Self>

Gets Pin out of self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
