Converting assignment operator from an `absl::StatusOr<U>`.

== Synopsis

Declared in `<absl/status/statusor.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<typename U>
requires internal_statusor::IsStatusOrAssignmentValid<
                                  T, const U&, false>::value
xref:absl/StatusOr.adoc[StatusOr]&
operator=(xref:absl/StatusOr.adoc[StatusOr<U>] const& other);
----

== Description

Creates an `absl::StatusOr<T>` through assignment from an `absl::StatusOr<U>` when:

* Both `absl::StatusOr<T>` and `absl::StatusOr<U>` are OK by assigning `U` to `T` directly. * `absl::StatusOr<T>` is OK and `absl::StatusOr<U>` contains an error code by destroying `absl::StatusOr<T>`'s value and assigning from `absl::StatusOr<U>' * `absl::StatusOr<T>` contains an error code and `absl::StatusOr<U>` is OK by directly initializing `T` from `U`. * Both `absl::StatusOr<T>` and `absl::StatusOr<U>` contain an error code by assigning the `Status` in `absl::StatusOr<U>` to `absl::StatusOr<T>`

These overloads only apply if `absl::StatusOr<T>` is constructible and assignable from `absl::StatusOr<U>` and `StatusOr<T>` cannot be directly assigned from `StatusOr<U>`.

== Return Value

A reference to `*this`.
