Struct async_dup::Arc

pub struct Arc<T>(pub Arc<T>);

A reference-counted pointer that implements async I/O traits.

This is just a wrapper around std::sync::Arc that adds the following impls:

• impl<T> AsyncRead for Arc<T> where &T: AsyncRead {}
• impl<T> AsyncWrite for Arc<T> where &T: AsyncWrite {}
• impl<T> AsyncSeek for Arc<T> where &T: AsyncSeek {}

Implementations

impl<T> Arc<T>

pub fn new(data: T) -> Arc<T>

Constructs a new Arc<T>.

Examples

use async_dup::Arc;

let a = Arc::new(7);
