#[repr(C)]
pub struct ARefs<'a, U: ?Sized>(_);
Expand description
ARefs is a version of ARef that implements Send.
It works just like ARef, except that its owner must implement Send, and thus
the struct implements Send as well.
Creates a new ARefs from what the ARefs points to.
use reffers::ARefs;
let aref = ARefs::new(Box::new(43));
assert_eq!(*aref, 43);
Maps the ARefs’ target to something reachable from the target.
use reffers::ARefs;
let aref: ARefs<[u8]> = vec![0u8, 5, 7].into();
assert_eq!(*aref.map(|s| &s[1]), 5);
Like map, but with Result passthrough.
use reffers::ARefs;
let aref = ARefs::<[u8]>::from(vec![0u8, 5, 7]);
assert_eq!(aref.try_map(|s| s.get(9).ok_or(())), Err(()));
Removes the type information that this struct is Send + Sync.
Converts this type into a shared reference of the (usually inferred) input type.
Immutably borrows from an owned value.

The resulting type after dereferencing.
Dereferences the value.
Converts to this type from the input type.
Compares and returns the maximum of two values.

This method tests for
self
and
other
values to be equal, and is used
by
==
.

This method tests for
!=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.

This method returns an ordering between
self
and
other
values if one exists.

This method tests less than (for
self
and
other
) and is used by the
<
operator.

Calls U::from(self)

That is, this conversion is whatever the implementation of
From<T> for U
chooses to do.

Performs the conversion.
