[−][src]Struct assert_unmoved::AssertUnmoved
A type that asserts that the underlying type is not moved after being pinned and mutably accessed.
See crate level documentation for details.
Implementations
impl<T> AssertUnmoved<T>
[src]
pub const fn new(inner: T) -> Self
[src]
Creates a new AssertUnmoved
.
pub const fn get_ref(&self) -> &T
[src]
Gets a reference to the underlying type.
Unlike get_mut
method, this method can always called.
You can also access the underlying type via Deref
impl.
pub fn get_mut(&mut self) -> &mut T
[src]
Gets a mutable reference to the underlying type.
Note that this method can only be called before pinned since AssertUnmoved
is !Unpin
.
pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut T>
[src]
Gets a pinned mutable reference to the underlying type.
Examples
Implement own Stream
trait for AssertUnmoved
.
use assert_unmoved::AssertUnmoved; use std::{ pin::Pin, task::{Context, Poll}, }; pub trait MyStream { type Item; fn poll_next(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Option<Self::Item>>; } impl<S: MyStream> MyStream for AssertUnmoved<S> { type Item = S::Item; fn poll_next(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Option<Self::Item>> { self.get_pin_mut().poll_next(cx) } }
