:mrdocs:

Constructs a new `StatusOr<T>` from a value convertible to `Status`.

== Synopsis

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

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

== Description

Constructs a new `absl::StatusOr<T>` with a non‐ok status. After calling this constructor, `this‐>ok()` will be `false` and calls to `value()` will crash, or produce an exception if exceptions are enabled.

The constructor also takes any type `U` that is convertible to `absl::Status`. This constructor is explicit if an only if `U` is not of type `absl::Status` and the conversion from `U` to `Status` is explicit.

REQUIRES: !Status(std::forward<U>(v)).ok(). This requirement is DCHECKed. In optimized builds, passing absl::OkStatus() here will have the effect of passing absl::StatusCode::kInternal as a fallback.

== Parameters
