visiting_ref

Container types that asynchronously return ownership of a value to another context upon exiting scope.

• Documentation
• Release notes

This crate provides VisitingRef and VisitingMut, two container types that effectively allow for safe "borrowing" of values through temporary transference of ownership between two separate contexts. These types wrap a given value, only allowing a reference to the value to be taken while the container is active. Upon exiting scope, the owned value is automatically sent back to another context asynchronously.

Usage

Add this to your Cargo.toml:

[dependencies]
visiting_ref = "0.2"

Now you can use VisitingRef and VisitingMut types in your code:

use visiting_ref::VisitingRef;

More details and example code can be found in the crate documentation.
