[−][src]Crate pin_project
A crate for safe and ergonomic pin-projection.
Examples
#[pin_project]
attribute creates projection types
covering all the fields of struct or enum.
use pin_project::pin_project; use std::pin::Pin; #[pin_project] struct Struct<T, U> { #[pin] pinned: T, unpinned: U, } impl<T, U> Struct<T, U> { fn method(self: Pin<&mut Self>) { let this = self.project(); let _: Pin<&mut T> = this.pinned; // Pinned reference to the field let _: &mut U = this.unpinned; // Normal reference to the field } }
code like this will be generated
See #[pin_project]
attribute for more details, and
see examples directory for more examples and generated code.
