Crate extend_mut 

This crate provides a safe way to extend the lifetime of a exclusive reference.

extend_mut allows for safe extension of the lifetime of a exclusive reference with a blocking closure.

[extend_mut_async] is similar to extend_mut, but it is async and requires a linear type be safe - but Rust does not have linear types yet, so it is unsafe.

Traits

ExtendMut

Trait designed to allow extending the lifetime of a mutable reference. It does not currently support async, contributions are welcome.

IntoExtendMutReturn

Trait designed to allow returning both &mut T and (&mut T, R), as well as other uses.

Functions

extend_mut

Extends the lifetime of a mutable reference. f must return the same reference that was passed to it, otherwise it will abort the process. You can still use this in async context, if you will call it on every poll, instead of on future creation (see poll_fn).
